Surface wave modes of a multilayered medium backed by a perfectly conducting ground plane: computation of propagation constants
Surface wave modes provide a mechanism for propagation of electromagnetic energy parallel to the surface of a multilayered medium, backed by a perfect electric conductor. The problem is made tractable by restricting the surfaces of the layers and the conductor to planes of infinite extent. As shown in this report, the surface waves are determined by complex poles of the reflection coefficient. A numerical technique is developed to compute these complex poles from which the surface wave propagation constants immediately follow. To keep this report brief, numerical results are given only for the first surface wave pole that appears above cutoff. The effects on the lossy-propagation constants of placing thin, lossy-dielectric and magnetic layers at various locations within a dielectric layer are studied as a function of frequency. 3 refs., 36 figs.
