MICROWAVE INVESTIGATION OF THE DIELECTRIC WAVE GUIDE PROPAGATION BY MAGNETO-IONIC DUCTS

A description is presented of the theoretical and experimental work performed on the propagation of electromagnetic waves along plasma columns in logitudinal magnetic fields. Theoretical work includes: completion of the basic theory for propagation along plasma columns in magnetic fields; derivation of Brillouin diagrams; and discussion of particularly significant limits and preliminary analyses of the non-uniform plasma case. Experimental work includes: measurements of basic propagation parameters; transmitted signal; wavelength and group velocity; and of physical plasma parameters as the electron density.
