Hi,
I was wondering about plasmonic THz and higher frequencies, when they propagate in copper the losses are extremely high due to the high accelerations of electrons radiating losses. I saw some new info on using metamaterials to "reduce electrons mass to near zero" using alternate thin layers of material with positive and negative permittivity:
I was wondering if this is a similar concept to a coax transmission line for RF, in that it prevents losses/radiation until the antenna? If a stripline transmission line is put on a PCB for THz frequencies using the nanometer thick alternate layers from that paper would that work to allow longer THz wires with low losses?
cheers, Jamie
