Characterization of a magnetoplasma integrated channel waveguide using FD-FD method

Abstract

The finite-difference in the frequency-domain (FD-FD) method is used here to study the propagation characteristics of an integrated channel waveguide, consisting of a plasma controlled by a mag,magnetostatic field (magnetoplasma). The dependence relation between resonance and cyclotron frequency collision frequency, channel dimensions, and plasma frequency is shown. The formulation is developed in terms of the transverse magnetic field components such that the problem is transformed into a conventional eigenvalue problem. The elimination of the spurious modes is obtained with the implicit inclusion of del.(B) over bar B = 0. (C) 1998 John Wiley & Sons, Inc.
