Erm... no. A maser is a low-frequency laser; see http://en.wikipedia.org/wiki/Maser\. You're thinking of TEMPEST. Again, refer to the Tempest - Wikipedia for details.

I'm also thinking of phase-conjugate mirrors, phased-array radars, RF cages, etc. But you are correct I have never bothered to nail down the details...

Shred your old hard-drives, guys! (-;
