Numerical simulation of the fundamental mode of a magnetoplasma rod surrounded by a lossless dielectric layer

The propagation characteristics of magnetoplasma waveguide coated with a fi nite thickness of dielectric material are presented. Because the boundary c onditions at all interfaces can be represented by the matrix equations, the characteristic equation can be obtained by successively using the matrix m anipulations. The dependence relations of attenuation and dispersion of the fundamental mode with plasma frequency, collision frequency, and electron cyclotron frequency are shown.
