Viridi 1 and Hendro 2 1Nuclear Physics and Biophysics, Institut Teknologi Bandung, Bandung 40132, Indonesia 2Theoretical High Energy Physics and Instrumentation, Institut Teknologi Bandung, Bandung 40132, Indonesia [email protected], [email protected] Abstract Trace of ray deviated by a prism, which is common in a TIR (total internal reflection) 2013 measurement system, is sometimes difficult to manage, especially if the prism is an Oct equilateral right angle prism (ERAP). The point where the ray is reflected inside the right- 2 1 angle prism is also changed as the angle of incident ray changed. In an ATR (attenuated total reflectance) measurement system, range of this point determines size of sample. Using JavaScript and HTML5 model and visualization of ray tracing deviated by an ERAP is perform and reported in this work. Some data are obtained from this visualization and an empirical relations between angle of incident ray source θS , angle of ray detector hand θ D′ , [physics.optics] and angle of ray detector θ D are presented for radial position of ray source RS = 25 cm , v1 radial position of ray detector RD = 20 cm , height of right-angle prism t =15 cm , and 0000 . 0 refractive index of the prism n = 5.1 . 1 Keywords: deviation angle, equilateral right angle prism, total internal reflection, JavaScript, HTML5.

The use of such materials has been proposed for numerous applications including sub-diffraction limit imaging and electromagnetic cloaking. While these materials were first developed to work at microwave frequencies, scaling them to optical wavelengths has involved both fundamental and engineering challenges. Among these challenges, optical metamaterials tend to absorb a large amount of the incident light and furthermore, achieving devices with such materials has been difficult due to fabrication constraints associated with their nanoscale architectures. The objective of this dissertation is to describe the progress that I have made in overcoming these challenges in achieving low loss optical metamaterials and associated devices. The first part of the dissertation details the development of the first bulk optical metamaterial with a negative index of refraction.

Photocopying permitted by license only SURFACE PLASMON ENHANCED EVANESCENT WAVE LASER LINAC T. H. KOSCHMIEDER* Department ofPhysicsIRLM5.208, University ofTexas at Austin, Austin, TX 78712 (Received 17 January 1992; in final form 25 September 1992) The grating laser linac concept of Palmer will be modified to incorporate a surface plasmon excitation in the visible part of the optical spectrum. Both grating and prism coupling of light to the surface plasmon will be discussed. It will be shown that phase matching between a relativistic particle and the surface plasmon can be achieved. Finally calculations will be presented showing that accelerations up to 14 GeV1m for a grating and up to 7 GeV1m for a prism could be obtained for incident power densities less than a nominal damage threshold. KEY WORDS: Laser-beam accelerators, Surface plasmons INTRODUCTION There is an ongoing interest in increasing the exit energy of particles from linacs. One possibility of achieving this is by PalmerI who showed that light incident upon a grating ? at skew angles could achieve very high accelerations (GeV1m). The relativistic particles travel just above the grating and are accelerated by coupling to evanescent waves. One effect that can occur for light incident upon a metal grating is the excitation of 2 a surface plasmon. Surface plasmon excitationc in the visible part of the spectrum will be explored in this paper. It will be shown that surface plasmon excitation in the visible part of the spectrum can be used to accelerate relativistic particles.

  • Modeling of Total Internal Reflection (TIR) Prism Abstract
    Modeling of Total Internal Reflection (TIR) Prism Abstract In this example, we illustrate the modeling of interference and vignetting effects at a total internal reflection (TIR) prism, where these effects are appearing especially for the transmitted part of the light. The discussed type of prism usually consist of two parts, which are glued together with a material of a slightly different refractive index. Dependent on the characteristics of the impinging light, vignetting as well as interference effects are appearing, which are introduced by the narrow gap between both prism parts. Task Description An optical system, that contains a total internal reflection (TIR) prism, is modeled. Due to the gap of the prism, which exhibits a slightly different refractive index, interesting effects may appear: - Multiple reflections occur at the prism gap. Hence an interference pattern can be observed for instance for transmitted part of the light. - With larger divergence of the source or larger tilt angle of the prism gap, vignetting effect can be observed in addition. - Of course, vignetting and interference can appear in combination.

  • Beam Manipulation: Prisms Vs. Mirrors
    OpticalOptical ComponentsCompone Beam manipulation: prisms vs. mirrors Andrew Lynch, Edmund Optics Inc., Barrington, NJ, USA Kai Focke, Edmund Optics GmbH, Karlsruhe, Germany Designers of beam manipulation and imaging systems often encounter the need to fold their optical layout into a more compact form, or to redirect light to the next component. In either case, the choice inevitably arises between mirrors, or alternatively, prisms. Solutions may often be found either way, but making the best selection up-front could save the designer from potential problems later.

  • PROBLEM 2 – 20 Points
    PROBLEM 1 - 10 points [5 points] (a) Three media are placed on top of one another. A ray of light starting in medium 2 experiences total internal reflection at the top interface but some of the light refracts into medium 3 when the ray reaches the bottom interface. If the two interfaces are parallel, rank the media by their index of refraction, from largest to smallest. [ ] n1>n2>n3 [ ] n1>n3>n2 [ ] n2>n1>n3 [ X ] n2>n3>n1 [ ] n3>n1>n2 [ ] n3>n2>n1 [ ] There is not enough information given above to decide. [ ] None of the above Briefly justify your answer: For total internal reflection to occur at the interface between medium 2 and medium 1, medium 2 must have a larger index of refraction than medium 1, and the angle of incidence exceeds the critical angle. We have the same angle of incidence at the interface between medium 2 and medium 3, where the beam in medium 3 bends away from the normal. Medium 3 must have a smaller index of refraction than medium 2 (so, medium 2 has the largest index of refraction). We have the same angle of incidence at both interfaces, but at the lower interface the angle of incidence is less than the critical angle. Thus, the index of refraction of medium 3 must be closer to that of medium 2 than is the index of refraction of medium 1. [5 points] (b) Medium 3 is now changed, and the rays follow the paths shown at right. Once again rank the media by their index of refraction, from largest to smallest.

  • The Play of Colours of Prisms
    The play of colours of prisms Amelia Carolina Sparavigna Institute of Fundamental Physics and Nanotechnology Department of Applied Science and Technology Politecnico di Torino, C.so Duca degli Abruzzi 24, Torino, Italy A short history of prisms from Lucius Anneus Seneca to George Ravenscroft The first scientific paper written by Newton was on the compound nature of white light, a paper where he described his experiments with prisms and the spectrum produced by the light. Newton had performed the experiments, probably between 1664 and 1667, in Woolsthorpe and Cambridge, using several glass prisms [1]. These glass artifacts existed and were sold at the country fairs to be used for the "play of colours", that is, to see the rainbow colours looking through them. This phenomenon of white light dispersion, created by crystals and glasses, was well known from ancient times and reported by Latin writers. Newton, experimenting with glass to improve optical instruments, explained that the play of colours was inside the nature of light. Few years after the Newton's studies, the development of lead glasses allowed new applications for the play of colours. Here a short history of prisms from Seneca to Ravenscroft. 1. Seneca, Pliny and their prisms A Latin writer, Lucius Anneus Seneca, was fascinated by prisms. In his Natural Questions, [2,3], he told that there existed some glass rods commonly made in two forms: striated, and with many angles. If they received the sun's rays obliquely, they create the colours as it is usually seen in a rainbow. It seems therefore that the glassmakers were producing such rods for observing the play of colours.

  • Mantle Cloaks Based on the Frequency Selective Metasurfaces Designed by Bayesian Optimization Received: 11 June 2018 F
    www.nature.com/scientificreports OPEN Mantle Cloaks Based on the Frequency Selective Metasurfaces Designed by Bayesian Optimization Received: 11 June 2018 F. F. Qin1, Z. Z. Liu 1, Q. Zhang1, H. Zhang 2 & J. J. Xiao1 Accepted: 3 September 2018 We propose a full optimization procedure for designing mantle cloaks enclosing arbitrary objects, Published: xx xx xxxx using sub-wavelength conformal frequency selective surface (FSS). Rely on the scattering cancellation principle of mantle cloak characterized by an average surface reactance, a personal computer can achieve this design procedure. By combing a Bayesian optimization (BO) with an electromagnetic solver, we can automatically fnd the optimal parameters of a conformal mantle cloak which can nearly cancel the scattering from the enclosed objects. It is shown that the results obtained by our method coincide with those from a rigorous analytical model and the numerical results by full parametric scanning. The proposed methodology opens up a new route for realizing ultra-wideband illusion scattering of electromagnetic wave, which is important for stealth and microwave applications. In the past decade, much attention has been paid to the concept and realization of electromagnetic cloaks, which is one of the most interesting applications of metamaterials and metasurfaces1–9. Coordinate transformation cloaking method10–12 is arguably the most successful approach that has been experimentally realized in radio fre- quency11, near infrared, and the visible7,13–15. Te principle of this technique is that by utilizing specifc anisotropy and inhomogeneity profles of the surrounding metamaterials (cloak) around an object, the electromagnetic wave inside the cloak can be bent and make the object efectively invisible.
