摘要
A versatile numerical method is used to solve the plasmonpolariton dispersion relation for a planar thin metal film geometry. A complete description of the variation of effective-mode index and propagation length with metal thickness and cover index is presented for all four modes. The spatial distribution of these modes is calculated explicitly. The effect of a nonideal metal film and of dielectric loss in the cover material is considered.
