I seem to remember a Art Bell show a few years back('99 or 00) that dealt with this.
Supposedly using lasers and some frequencies to get a rather non-physical manifestation of what Greer termed "ships" that would beam lights back
If I remember correctly, he even invited Art to come do a broadcast on location which Art left open(but never happened).
I'm not sure there's any real "meat" to it though, just recounting what I remember.
