NIST Finds ‘Metafilms’ Can Shrink Radio, Radar Devices

This is from the March 18, 2008 issue of NIST Tech Beat. It seems to me this technology could also be used at UHF, VHF, and perhaps even HF frequencies……Dan
Recent research at the National Institute of Standards and Technology (NIST) has demonstrated that thin films made of “metamaterials”—manmade composites engineered to offer strange combinations of [...]

Microwave Hacking, Anyone?
