Some plasma antennas feature low insertion loss (http://en.wikipedia.org/wiki/Insertion_loss) and capable of replacing conventional switching technologies RF MEMS or RF switches (PIN Diodes or FETs). The technology gets cheaper with increased frequency, which is a big plus. There are stealth and wide-band surveillance applications. Would love to play with one.

We're abstracting everything these days as soft-objects. Soon it will be Software defined Consciousness. The Singularity approaches! :)
