Christiansen Submitted tot eh Department of Materials Science and Engineering on May 25, 2017 in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in Materials Science and Engineering ABSTRACT Research on biomedical applications of magnetic nanoparticles (MNPs) has increasingly sought to demonstrate noninvasive actuation of cellular processes and material responses using heat dissipated in the presence of an alternating magnetic field (AMF). By modeling the dependence of hysteresis losses on AMF amplitude and constraining AMF conditions to be physiologically suitable, it can be shown that MNPs exhibit uniquely optimal driving conditions that depend on controllable material properties such as magnetic anisotropy, magnetization, and particle volume. “Magnetothermal multiplexing,” which relies on selecting materials with substantially distinct optimal AMF conditions, enables the selective heating of different kinds of collocated MNPs by applying different AMF parameters. This effect has the potential to extend the functionality of a variety of emerging techniques with mechanisms that rely on bulk or nanoscale heating of MNPs. -

Metamaterial is a word that seems both familiar and mysterious to the layman: on the one hand, this research area born twenty years ago at the interface between physical and engineering sciences requires a high level of expertise to be investigated with advanced theoretical and experimental methods; and on the other hand electromagnetic paradigms such as negative refraction, super lenses and invisibility cloaks have attracted attention of mass media. Even the origin and meaning of the word metamaterial (formed of the Greek prefix μετά meaning beyond or self and the Latin suffix materia, meaning material) remains elusive. -

The Quest for the Superlens
THE QUEST FOR THE CUBE OF METAMATERIAL consists of a three- dimensional matrix of copper wires and split rings. Microwaves with frequencies near 10 gigahertz behave in an extraordinary way in the cube, because to them the cube has a negative refractive index. The lattice spacing is 2.68 millimeters, or about one tenth of an inch. 60 SCIENTIFIC AMERICAN COPYRIGHT 2006 SCIENTIFIC AMERICAN, INC. Superlens Built from “metamaterials” with bizarre, controversial optical properties, a superlens could produce images that include details fi ner than the wavelength of light that is used By John B. Pendry and David R. Smith lmost 40 years ago Russian scientist Victor Veselago had Aan idea for a material that could turn the world of optics on its head. It could make light waves appear to fl ow backward and behave in many other counterintuitive ways. A totally new kind of lens made of the material would have almost magical attributes that would let it outperform any previously known. The catch: the material had to have a negative index of refraction (“refraction” describes how much a wave will change direction as it enters or leaves the material). All known materials had a positive value. After years of searching, Veselago failed to fi nd anything having the electromagnetic properties he sought, and his conjecture faded into obscurity. A startling advance recently resurrected Veselago’s notion. In most materials, the electromagnetic properties arise directly from the characteristics of constituent atoms and molecules. Because these constituents have a limited range of characteristics, the mil- lions of materials that we know of display only a limited palette of electromagnetic properties. -
The Demon Haunted World
THE DEMON- HAUNTED WORLD Science as a Candle in the Dark CARL SAGAN BALLANTINE BOOKS • NEW YORK Preface MY TEACHERS It was a blustery fall day in 1939. In the streets outside the apartment building, fallen leaves were swirling in little whirlwinds, each with a life of its own. It was good to be inside and warm and safe, with my mother preparing dinner in the next room. In our apartment there were no older kids who picked on you for no reason. Just the week be- fore, I had been in a fight—I can't remember, after all these years, who it was with; maybe it was Snoony Agata from the third floor— and, after a wild swing, I found I had put my fist through the plate glass window of Schechter's drug store. Mr. Schechter was solicitous: "It's all right, I'm insured," he said as he put some unbelievably painful antiseptic on my wrist. My mother took me to the doctor whose office was on the ground floor of our building. With a pair of tweezers, he pulled out a fragment of glass. Using needle and thread, he sewed two stitches. "Two stitches!" my father had repeated later that night. He knew about stitches, because he was a cutter in the garment industry; his job was to use a very scary power saw to cut out patterns—backs, say, or sleeves for ladies' coats and suits—from an enormous stack of cloth. Then the patterns were conveyed to endless rows of women sitting at sewing machines. -
Fundamentals and Applications in Narrowband Transmission Color Filtering
Nanophotonic Structures: Fundamentals and Applications in Narrowband Transmission Color Filtering Thesis by Dagny Fleischman In Partial Fulfillment of the Requirements for the degree of Doctor of Philosophy CALIFORNIA INSTITUTE OF TECHNOLOGY Pasadena, California 2019 Defended June 22, 2018 ii © 2019 Dagny Fleischman ORCID: 0000-0003-2913-657X All rights reserved iii ACKNOWLEDGEMENTS This has been an incredible journey, and it would not have come together without the support and wisdom of a phenomenal group of people. They say it takes a village to raise a child, and through this experience I’ve seen that is equally applicable to graduate students, because it has certainly taken a village to raise me. First and foremost, I want to thank my advisor, Harry Atwater. I am incredibly grateful for the freedom Harry has given me to turn my childhood fascination with colors into an extremely gratifying research path. Harry embodies everything a scientist and faculty member should be: keenly intelligent, insatiably curious, and someone who cares as deeply about his students as he does the science he is studying. As much as he has contributed to my development as a scientist, he has added even more to my understanding of just how much an individual can contribute to science and technology. We often joke in lab that “we can’t all be Harry Atwater” and I will always be deeply impressed by the nearly impossibly high bar he has set for us all to aspire to. In addition to Harry’s mentorship, I was extremely fortunate to have Luke Sweat- lock as a mentor during the early years of my PhD. -
Metamaterial-Based Flat Lens: Wave Concept Iterative Process Approach
Progress In Electromagnetics Research C, Vol. 75, 13–21, 2017 Metamaterial-Based Flat Lens: Wave Concept Iterative Process Approach Mohamed K. Azizi1, *, Henri Baudrand2, Lassaad Latrach1, and Ali Gharsallah1 Abstract—Metamaterials left-hand negative refractive index has remarkable optical properties; this paper presents the results obtained from the study of a flat metamaterial lens. Particular interest is given to the interaction of electromagnetic waves with metamaterials in the structure of the lens Pendry. Using the new approach of the Wave Concept Iterative Process (WCIP) based on the auxiliary sources helps to visualize the behavior of the electric field in the metamaterial band and outside of its interfaces. The simulation results show an amplification of evanescent waves in the metamaterials with an index of n = −1, which corresponds to a resonance phenomenon to which the attenuation solution is canceled, leaving only the actual growth of these waves. This amplification permits the reconstruction of the image of the source with a higher resolution. 1. INTRODUCTION The way of negative refraction has sparked a rare craze after passionate debate generated by controversies on electromagnetic models. In 1968, the Russian Victor Veselago invented the converging lens plate [1]. In the late 1990s, Pendry and his team carried out work on metal wire networks (“wire medium”) [2, 3] and (split-ring resonators or SRR) [4]. Given the difficulty to achieve super-lenses, teams of researchers developed other systems exploiting the characteristics of metamaterials to achieve a sub-wave length resolution. These new devices include the wireless networks [5, 6] operating in the pipeline system, networks of nanoparticles [7], and the hyper-lenses using structures of spherical and anisotropic form [8–10]. -
Bending the Laws of Optics with Metamaterials: an Interview With
National Science Review INTERVIEW 5: 200–202, 2018 doi: 10.1093/nsr/nwx118 Advance access publication 20 September 2017 Special Topic: Metamaterials Bending the laws of optics with metamaterials: an interview with John Pendry By Philip Ball Downloaded from https://academic.oup.com/nsr/article/5/2/200/4209243 by guest on 23 September 2021 Metamaterials show us that nature’s laws might not always be as fixed as they seem to be. One of the laws of optics, for example, statesthat a light ray passing from one transparent medium to another—air to water or glass, say—is bent at the interface by an amount that depends on the so-called refractive indices of the two media. And all transparent materials have a refractive index greater thanthatofa vacuum (or, roughly speaking, of air), which is set equal to 1. Or do they? In the 1960s, the Russian physicist Victor Veselago explained what would be needed, in theory, for a material to have a refractive index that is not only less than 1 but in fact negative, so that itbends light the ‘wrong way’. Veselago’s idea was all but forgotten until it was unearthed in the late 1990s by electrical engineer David Smith. He was wondering ifit might be possible to make a ‘scaled-up’ version of such a material, built from ‘artificial atoms’ and later called a metamaterial, which could show this effect at longer wavelengths than those of light, in the microwave part of the spectrum. By happy coincidence, physicist SirJohn Pendry of Imperial College London, UK, had already come up with a prescription for making a similar structure from loops of wire. -
Quantum Model of Ferrofluid Motion
Quantum Model of Ferrofluid Motion Ferrofluids, with their mesmeric display of shape-shifting spikes, are a favorite exhibit in science shows. These eye-catching examples of magnetic fields in action could become even more dramatic through computational work that captures their motion. [37] Case Western Reserve University researchers are working to change that. They have pioneered a new approach called Magnetic Resonance Fingerprinting, which uses more sensitive scanning techniques that they expect could detect whether treatments are working after just one dose of chemo. [36] The standard approach to building a quantum computer with majoranas as building blocks is to convert them into qubits. However, a promising application of quantum computing—quantum chemistry—would require these qubits to be converted again into so-called fermions. [35] Scientists have shown how an optical chip can simulate the motion of atoms within molecules at the quantum level, which could lead to better ways of creating chemicals for use as pharmaceuticals. [34] Chinese scientists Xianmin Jin and his colleagues from Shanghai Jiao Tong University have successfully fabricated the largest-scaled quantum chip and demonstrated the first two-dimensional quantum walks of single photons in real spatial space, which may provide a powerful platform to boost analog quantum computing for quantum supremacy. [33] To address this technology gap, a team of engineers from the National University of Singapore (NUS) has developed an innovative microchip, named BATLESS, that can continue to operate even when the battery runs out of energy. [32] Stanford researchers have developed a water-based battery that could provide a cheap way to store wind or solar energy generated when the sun is shining and wind is blowing so it can be fed back into the electric grid and be redistributed when demand is high. -

A Metamaterial Path Towards Optical Integrated Nanocircuits Abstract Metamaterials are known to demonstrate exotic electromagnetic and optical properties. The extra control over manipulation of waves and fields afforded by metamaterials can be exploited towards exploring various platforms, e.g., optical integrated circuits. Nanophotonic integrated circuits have been the topic of past and ongoing research in multiple fields including, but not limited o,t electrical engineering, optics and materials science. In the present work, we theoretically study and analyze metamaterial properties that can be potentially utilized in the future design of optical integrated circuits. On this path, we seek inspiration from electronics to tackle multiple issues in developing such layered nanocircuitry. We identify modularity, directionality/isolation and tunability as three useful features of electronics and we theoretically explore mimicking them in nanoscale optics. Using epsilon-near-zero (ENZ) and mu-near- zero (MNZ) properties we propose concepts to transplant some aspects of modular design of electronic passive circuits and filters into nanophotonics. We also exploit ENZ materials to develop “transformer- like” functionality in optical nanocircuits.
