Abstract
By applying the variational reaction theory, a variational equation is established for handling wave propagation in a parallel-plate guide within which a magnetized inhomogeneous lossy plasma slab is inserted. The equation is then solved by the finite-element method along with the frontal solution algorithm. With such an approach, the reflection coefficient and the field distribution in the slab are obtained. In this study, the factors which may influence the propagation characteristics of the guide are studied. These factors include the plasma electron density, the strength and the direction of the static magnetic field, the width and the thickness of the slab, and the electron collision losses. A social modal expansion solution is also incorporated to investigate an anomalous numerical instability associated with the present numerical algorithm. © 1986 by The Electrical and Electronics Engineers, Inc.
