Long Distance Signaling Using Axion-like Particles
Abstract
Description
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 $g_{aγγ} > 5 \times 10^{- 8} {\text{GeV}}^{- 1}$.
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
