University of Otago physicists have used a small glass bulb containing an atomic vapor to demonstrate a new form of antenna for radio waves. The bulb was "wired up" with laser beams and could therefore be placed far from any receiver electronics.
I do think it can receive on many frequencies at once. But I think the Fourier transform won’t be able to untangle a signal if that signal is broadcast continuously on all frequencies.
Hmm alright, maybe I misunderstood that part, I was thinking that meant ability to broadcast a gamut of signal.
