Propagation of short-wavelength electromagnetic surface waves along the transition layer between two plasma-like half-spaces in the Voigt geometry

Abstract

The dispersion properties of surface type electromagnetic waves are studied. The waves are considered to propagate along a slab transition layer located between two infinite homogeneous plasma regions of different particle densities. The wavelength is assumed to be short as compared with the layer width. The waves propagate across a static magnetic field, which is parallel to the layer interface. The influence of the smoothness of the gradient of the plasma particle density within the layer on the surface wave propagation/disappearance is discussed. The conclusions derived in the present paper are of interest in the fields of plasma electronics, nano-technologies, plasma-antenna systems, plasma production, and magnetic confinement fusion.
