Re: [ATM] Superlens (negative refractive index)

Bob,

Yep, the optical components will be tricky, but considering the  
advancement in technology in the last couple of decades--heck even in  
the last ten years--it doesn't seem unrealistic.

The article didn't say it, but the way the structures were described/ 
explained--and having a degree in physics and astronomy--I surmised  
that these tricks were narrowband.  That being said, would us  
amateurs be able to do some funky things with radio astronomy in the  
21-cm realm?
