Abstract : The work performed under this Contract is described. Theoretical work includes: discussion of the basic quasi-static and exact theories for propagation along plasma slabs and columns in magnetic fields, derivation of Brillouin diagrams, calculations of electromagnetic power flows, extension of theory to the case of external metallic walls, comparison with whistlertype characteristics, approximate evaluations of propagation features in non-uniform and in warm plasma slabs. Experimental work includes: detection of plasma guided signals, measurements of their amplitudes, phase and group velocities, check measurements of the electron density. Most of the experimental results are interpreted in terms of the discussed theory. (Author)
