A new device built by physicists to generate radiation, and named a polarization synchrotron, is really making me scratching my head. The researchers say that the intensity of the radiation generated by their synchrotron declines more slowly with increasing distance from the source than would the emission from a conventional antenna. It "is proportional to 1/r, where r is the distance from the transmitter, rather than the 1/r2 associated with spherically decaying radiation."
Well, this is puzzling, but wait a minute, there is more. They also say "they can make the wave travel at greater than the speed of light (even though no physical quantity of charge travels superluminally)." In this article, PhysicsWeb reports that other physicists are skeptical.
Anyway, if they are right, this could pave the way for mobile phones communicating directly with satellites without any need for relay stations. You'll find more details and photographs in this overview.
