Long Distance Signaling Using Axion-like Particles

Abstract

The possible existence of axion-like particles could lead to a new type of long distance communication. In this work, basic antenna concepts are defined and a Friis-like equation is derived to facilitate long-distance link calculations. An example calculation is presented showing that communication over distances of 1000 km or more may be possible for $m_a<3.5$ meV and $g_{a\gamma \gamma }>5\times 10^{-8}{\text{GeV}}^{-1}$.

18 pages, including 3 figures Version 2 has been modified to show portions of the coupling-mass plane that may lead to long distance communication, rather than concentrating on an example using the PVLAS parameters
