Electromagnetic Wave Propagation in Periodic Media.
Abstract
The study investigates the propagation of electromagnetic waves in a rectangular waveguide which contains a periodically varying unidirectionally inhomogeneous medium. Variations of both permittivity and permeability in the direction of propagation are considered. It is shown that the solution to this problem leads to a form of the Hill differential equation. Two methods for solving this equation are presented. The first is Hill's method of solution and the second is a transmission matrix form of solution. A characteristic equation, derived from the Hill equation, is used to predict wave propagation characteristics. Several media are analyzed and passbands and stopbands are predicted for each configuration. The effects of varying medium period and parameters are studied. Experimental verification of a number of cases is presented and compared with predicted results.
