Optical surface plasmons at a metal-crystal interface with the Drude-Lorentz model for material permittivity

A. P. Misra, M. Shahmansouri, N. Khoddam

The theory of surface electromagnetic waves (SEMWs) propagating at optical frequencies along the interface of an isotropic noble metal [e.g., gold (Au)] and a uniaxial crystal [e.g…
