SURFACE WAVES ON A UNIAXIAL PLASMA SLAB; THEIR GROUP VELOCITY AND POWER FLOW

Abstract

The relation between group velocity and the velocity of energy transport for surface waves in plane-stratified, anisotropic, dispersive media is verified by direct calculation for the case of surface waves on a uniaxial, cold plasma slab located in free space. A superimposed D.C. magnetic field of infinite strength and parallel to the interface generates the uniaxial anisotropy in the slab. Surface waves having an arbitrary direction of propagation with respect to the D. C. magnetic field are considered. A useful graphical presentation of the dispersion relation is given, from which the direction of propagation of ''surface wave rays'' is directly obtained.
