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-inductors, nano-capacitors, and nano-resistors, are
discussed in terms of small nanostructures with different material properties.
Coupled nanocircuits and parallel and series combinations are also envisioned,
which may provide road maps for the synthesis of more complex nanocircuits in
the IR and visible bands. Ideas for the optical implementation of right-handed
and left-handed nano-transmission lines are also forecasted.Comment: 14 pages, 5 figures, submitted to Physical Review Letter
