Surface plasmons at uniaxial gratings: numerical study of the dispersion relation

摘要

In this work, we study the homogeneous problem (without incident wave), corresponding to a periodically corrugated surface which separates a uniaxial crystal from a metal. In order to analyze, in a second stage, the excitation of plasmons in conical mounting, we consider that the propagation direction of the plasmons is arbitrarily oriented.
