Abstract
This project seeks to investigate the behavior of a novel superluminal polarization current antenna in development by scientists at Los Alamos National Laboratory. At the high frequencies required for high-speed communications, currents can only flow on a very thin region near the surface of a conventional metal antenna. The Los Alamos approach instead uses a series of electrodes to drive a current of electrical polarization through the volume of a non-conducting material. Since the electrodes fire independently, the speed of the polarization wave can be faster than the speed of light, which yields a highly directional radiation pattern akin to a sonic boom. Through MATLAB simulations, we examine the relationship between physical antenna parameters and resulting radiation patterns of a spiral antenna geometry operating in the radio frequency range. Such an antenna has applications in telecommunications, particularly in communities with little to no access to wired last mile communications systems, as well as relevance to astronomy and, potentially, many other areas.
