Abstract

In this paper, we present the theoretical analysis of excitation of well-bounded oblique surface electromagnetic waves propagating along an anisotropically conducting interface of two different dielectrics by means of the attenuated-total-reflection method. The flat surface of the interface contains a one-dimensional array of thin metal wires. It has been assumed that both the lattice constant of the array and the diameter of the wires are far less than the wavelengths of the surface waves. The surface electromagnetic waves may propagate along the interface at frequencies that are far lower than the plasma frequency of a metal, and the electric field of the waves is always perpendicular to the wires in any propagation directions. It has been shown that the oblique surface electromagnetic waves can be excited by the TM-polarized electromagnetic wave which becomes partially polarized during the excitation.
