Circuit elements at optical frequencies: nano-inductors, nano-capacitors and nano-resistors
Nader Engheta, Alessandro Salandrino, Andrea Alu
We present some ideas for synthesizing nanocircuit elements in the optical domain using plasmonic and non-plasmonic nanoparticles. Three basic circuit elements, i.e., nano-inductor…
Metamaterial covers over a small aperture
Andrea Alu, Filiberto Bilotti, Nader Engheta +1
Recently, it has been experimentally shown by several other researchers in the physics community that a properly designed periodic corrugation of a metallic opaque screen may signi…
'Growing Evanescent Envelopes and Anomalous Tunneling' in Cascaded Sets of Frequency-Selective Surfaces in Their Stop Bands
Andrea Alu, Nader Engheta
The presence of wave tunneling and the 'growing evanescent envelope' for field distributions in suitably designed, periodically layered stacks of frequency selective surfaces (FSS)…
