Abstract
Waveguide modes propagating along the circular-cylinder silver nanowire on a silica substrate are calculated and studied using an in-house developed full-vector finite-element imaginary-distance beam propagation method (FV-FE-IDBPM). In particular, leaky-mode characteristics for the mode with field guided mainly at the top air-silver interface and that with field distributed mainly near the silver-substrate interface are presented and discussed based on high-resolution numerical analysis. Complex effective indices are accurately solved from which the modal propagation lengths are determined.
