Abstract
⺠We provide electrical circuit descriptions for bulk plasmons, single surface plasmons, and parallel-plate plasmons. ⺠Simple circuits can reproduce the exactly known frequency versus wave-vector dispersion relations for all these cases, with reasonable accuracy. ⺠The capacitance/unit length and the Faraday inductance/unit length, of a flat metal surface, are Câ²Â = 2(okW, and Lâ²Â = (o/2kW, respectively (where k is the wave-vector, and W is the width of the flat metal surface). ⺠The circuit paradigm directly provides a characteristic wave-impedance, Zo, that is rarely discussed in the context of plasmonics. ⺠The wave-impedance, Zo, is found to diverge at the nanoscale, thus allowing for optical voltage transformer action.
