GUIDED WAVES SUPPORTED BY LAYERS OF A LOSSY COMPRESSIBLE PLASMA,

Abstract

A planar slab of isotropic compressible lossy plasma is bounded either by free space on both sides or by free space and a ground plane, and is excited by line sources. After establishing the dispersion relations the power carried by the waves is calculated. The total power of the many waves which depend on the resonances of the plasma waves in the transverse dimension of the slab is about two orders of magnitude lower than the power of the surface waves guided along the plasma boundary for frequencies which are somewhat higher than the plasma frequency. The excitation efficiency of the transversely resonant waves is decreased for thick layers of a lossy plasma, but the losses can be neglected if the layer thickness is of the order of free space wavelength and the loss tangent of the plasma is less than 0.01.
