An ex citer system is provided for use in facilitating electromagnetic communication within an enclosed space. The system includes an exciter which may be in the form of a three dimensional hemispherical exciter or a two dimensional planar sector exciter depend ing on the size of the associated structure and the power requirements of operation. The exciter system operates in conjunction with a hub/controller network. The exciter system is adapted to induce a quasi-static evanescent field within the space and to thereby enable commumcations using the evanescent field at frequencies within an operational frequency range determined by the characteristics of the space. The exciter is mounted in opposition to a portion of a conductive framework within the enclosed space. In operation an coaxial connector connects the exciter to die hub/controller network with the central conductor connecting at a feed point to the exciter while the shield conductor is connected to the opposing conductive framework. In some embodiments a post acts as a curtain to enhance performance at tower frequencies. Improved communications systems and methods, however, may be desired to accommodate increasing commumcations to and from extraterrestrial bodies such as the moor and/or mars as more missions are sent to extraterrestrial bodies. More particularly, communications systems and methods may be desired to ac commodate increased commumcations between radio- terminals on the extraterrestrial body and a satellite orbiting a celestial body and/ or transceivers on earth. The present invention relates generally to wireless communications and more particularly to systems for internal commumcations within structures, at frequencies in the range of 0.5 to 100 MHz.

    1: For me, it was personal names with too many of the letter "q", "z", or "x". With apostrophes. Big indicator of "call a rabbit a smeerp"; and generally, a given name turns up on page 1... 2: Large scale conspiracies over large time scales that remain secret and don't fall apart. (This is not *explicitly* limited to SF, but appears more often in branded-cyberpunk than one would hope for a subgenre borne out of Bruce Sterling being politically realistic in a zine.) Pretty much *any* form of large-scale space travel. Low earth orbit, not so much; but, human beings in tin cans going to other planets within the solar system is an expensive multi-year endevour that is unlikely to be done on a more regular basis than people went back and forth between Europe and the americas prior to steam ships. Forget about interstellar travel. Any variation on the old chestnut of "robots/ais can't be emotional/creative". On the one hand, this is realistic because human beings have a tendency for othering other races with beliefs and assumptions that don't hold up to any kind of scrutiny (see, for instance, the relatively common belief in pre-1850 US that black people literally couldn't feel pain). On the other hand, we're nowhere near AGI right now and it's already obvious to everyone with even limited experience that AI can be creative (nothing is more creative than a PRNG) and emotional (since emotions are the least complex and most mechanical part of human experience and thus are easy to simulate).

  • Theory of Space Magnetic Sail Some Common Mistakes and Electrostatic Magsail
    1 Article MagSail after Cath for J 10 1 6 06 AIAA -2006 -8148 Theory of Space Magnetic Sail Some Common Mistakes and Electrostatic MagSail * Alexander Bolonkin C&R, 1310 Avenue R, #F -6, Brooklyn, NY 11229, USA T/F 718 -339 -4563, [email protected], http://Bolonki n.narod.ru Abstract The first reports on the “Space Magnetic Sail” concept appeared more 30 years ago. During the period since some hundreds of research and scientific works have been published, including hundreds of research report by professors at major famous universities. The author herein shows that all these works related to Space Magnetic Sail concept are technically incorrect because their authors did not take into consideration that solar wind impinging a MagSail magnetic field creates a particle m agnetic field opposed to the MagSail field. In the incorrect works, the particle magnetic field is hundreds times stronger than a MagSail magnetic field. That means all the laborious and costly computations in revealed in such technology discussions are us eless: the impractical findings on sail thrust (drag), time of flight within the Solar System and speed of interstellar trips are essentially worthless working data! The author reveals the correct equations for any estimated performance of a Magnetic Sail as well as a new type of Magnetic Sail (without a matter ring). Key words: magnetic sail, theory of MagSail, space magnetic sail, Electrostatic MagSail *Presented to 14th AIAA/AHI Space Planes and Hypersonic Systems and Technologies Conference , 6 - 9 Nov 2006 National Convention Centre, Canberra, Australia. Introduction The idea of utilizing the magnetic field to aggregate matter in space, harnessing a drag from solar wind or receiving a thrust from an Earth - charged particle beam is old.

  • Interstellar Communication: the Case for Spread Spectrum
    Interstellar Communication: The Case for Spread Spectrum David G Messerschmitta aDepartment of Electrical Engineering and Computer Sciences, 253 Cory Hall, University of California, Berkeley, California 94720-1770, USA, [email protected], 1-925-465-5740 Abstract Spread spectrum, widely employed in modern digital wireless terrestrial radio systems, chooses a signal with a noise-like character and much higher bandwidth than necessary. This paper advocates spread spectrum modulation for interstellar communication, motivated by robust immunity to radio- frequency interference (RFI) of technological origin in the vicinity of the receiver while preserving full detection sensitivity in the presence of natural sources of noise. Receiver design for noise immunity alone provides no basis for choosing a signal with any specific character, therefore failing to reduce ambiguity. By adding RFI to noise immunity as a design objective, the conjunction of choice of signal (by the transmitter) together with optimum detection for noise immunity (in the receiver) leads through simple probabilistic argument to the conclusion that the signal should possess the statistical properties of a burst of white noise, and also have a large time-bandwidth product. Thus spread spectrum also provides an implicit coordination between transmitter and receiver by reducing the ambiguity as to the signal character. This strategy requires the receiver to guess the specific noise-like signal, and it is contended that this is feasible if an appropriate pseudorandom signal is generated algorithmically. For example, conceptually simple algorithms like the binary expansion of common irrational numbers like π are shown to be suitable. Due to its deliberately wider bandwidth, spread spectrum is more susceptible to dispersion and distortion in propagation through the interstellar medium, desirably reducing ambiguity in parameters like bandwidth and carrier frequency.

  • The Search for Extraterrestrial Intelligence
    THE SEARCH FOR EXTRATERRESTRIAL INTELLIGENCE Are we alone in the universe? Is the search for extraterrestrial intelligence a waste of resources or a genuine contribution to scientific research? And how should we communicate with other life-forms if we make contact? The search for extraterrestrial intelligence (SETI) has been given fresh impetus in recent years following developments in space science which go beyond speculation. The evidence that many stars are accompanied by planets; the detection of organic material in the circumstellar disks of which planets are created; and claims regarding microfossils on Martian meteorites have all led to many new empirical searches. Against the background of these dramatic new developments in science, The Search for Extraterrestrial Intelligence: a philosophical inquiry critically evaluates claims concerning the status of SETI as a genuine scientific research programme and examines the attempts to establish contact with other intelligent life-forms of the past thirty years. David Lamb also assesses competing theories on the origin of life on Earth, discoveries of ex-solar planets and proposals for space colonies as well as the technical and ethical issues bound up with them. Most importantly, he considers the benefits and drawbacks of communication with new life-forms: how we should communicate and whether we could. The Search for Extraterrestrial Intelligence is an important contribution to a field which until now has not been critically examined by philosophers. David Lamb argues that current searches should continue and that space exploration and SETI are essential aspects of the transformative nature of science. David Lamb is honorary Reader in Philosophy and Bioethics at the University of Birmingham.

  • Magnetoshell Aerocapture: Advances Toward Concept Feasibility
    Magnetoshell Aerocapture: Advances Toward Concept Feasibility Charles L. Kelly A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Aeronautics & Astronautics University of Washington 2018 Committee: Uri Shumlak, Chair Justin Little Program Authorized to Offer Degree: Aeronautics & Astronautics c Copyright 2018 Charles L. Kelly University of Washington Abstract Magnetoshell Aerocapture: Advances Toward Concept Feasibility Charles L. Kelly Chair of the Supervisory Committee: Professor Uri Shumlak Aeronautics & Astronautics Magnetoshell Aerocapture (MAC) is a novel technology that proposes to use drag on a dipole plasma in planetary atmospheres as an orbit insertion technique. It aims to augment the benefits of traditional aerocapture by trapping particles over a much larger area than physical structures can reach. This enables aerocapture at higher altitudes, greatly reducing the heat load and dynamic pressure on spacecraft surfaces. The technology is in its early stages of development, and has yet to demonstrate feasibility in an orbit-representative envi- ronment. The lack of a proof-of-concept stems mainly from the unavailability of large-scale, high-velocity test facilities that can accurately simulate the aerocapture environment. In this thesis, several avenues are identified that can bring MAC closer to a successful demonstration of concept feasibility. A custom orbit code that dynamically couples magnetoshell physics with trajectory prop- agation is developed and benchmarked. The code is used to simulate MAC maneuvers for a 60 ton payload at Mars and a 1 ton payload at Neptune, both proposed NASA mis- sions that are not possible with modern flight-ready technology. In both simulations, MAC successfully completes the maneuver and is shown to produce low dynamic pressures and continuously-variable drag characteristics.

    Draft version November 17, 2017 INTERSTELLAR COMMUNICATION. III. OPTIMAL FREQUENCY TO MAXIMIZE DATA RATE Michael Hippke1 and Duncan H. Forgan2, 3 1Sonneberg Observatory, Sternwartestr. 32, 96515 Sonneberg, Germany 2SUPA, School of Physics & Astronomy, University of St Andrews, North Haugh, St Andrews, Scotland, KY16 9SS, UK 3St Andrews Centre for Exoplanet Science, University of St Andrews, UK ABSTRACT The optimal frequency for interstellar communication, using \Earth 2017" technology, was derived in papers I and II of this series (Hippke 2017a,b). The framework included models for the loss of photons from diffraction (free space), interstellar extinction, and atmospheric transmission. A major limit of current technology is the focusing of wavelengths λ < 300 nm (UV). When this technological constraint is dropped, a physical bound is found at λ ≈ 1 nm (E ≈ keV) for distances out to kpc. While shorter wavelengths may produce tighter beams and thus higher data rates, the physical limit comes from surface roughness of focusing devices at the atomic level. This limit can be surpassed by beam-forming with electromagnetic fields, e.g. using a free electron laser, but such methods are not energetically competitive. Current lasers are not yet cost efficient at nm wavelengths, with a gap of two orders of magnitude, but future technological progress may converge on the physical optimum. We recommend expanding SETI efforts towards targeted (at us) monochromatic (or narrow band) X-ray emission at 0.5-2 keV energies. 1.
