Abstract

The theoretical analysis of transverse electric surface waves in ferrite medium surrounded by isotropic plasma layers is presented in this manuscript. Maxwell’s equations in differential form are used, and we impose the boundary conditions to acquire the dispersion relation to formulate the proposed structure. The influence of number density, separation distance between the layers of plasma, and dielectric permittivity of ferrite film on the normalized propagation constant is studied. It is concluded from the result obtained that if the number density and values of dielectric permittivity of ferrite film increases the propagation constant Re(β) tends to decreases whereas the increase in separation distance between the layers of plasma tends to increase the propagation constant Re(β). Furthermore, to verify the surface waves, the normalized field distribution for plasma medium as well as ferrite medium are also presented in this manuscript. The present work has potential applications in communication, drug delivery, cancer treatment, and ferrite sensing waveguide structures in the GHz frequency regime.

Summary

Introduction

Investigation of the electromagnetic traits of plasma waveguide structures reveals attractive features that are very significant for potential applications in communication, cancer treatment, advancement in methods of charge particle acceleration, transport of high current charge particle beams, and generation of high-power electromagnetic radiation [1,2,3]. The presented work of this manuscript deals with a waveguide made of a plasma-ferrite-plasma planar interface in the GHz operating surface wave frequency. The influence of the number density of electrons, separation distance, and dielectric permittivity of the ferrite material on the propagation constant is studied.
