Abstract :
With growing interest in satellite sensors applications in sub-millimeter wave regions, signal control techniques and components are becoming increasingly important at these frequencies. This requires the complete apprehension and characterization of modal and performance plane features of such non-reciprocal structures. Modal analysis for GaAs Magnetoplasma parallel plate waveguide and gyroelectric performance factor analysis for GaAs Magnetoplasma ridged parallel plate waveguide is presented. Modal analysis in the extra-ordinary wave resonance region for parallel plate waveguide after the inclusion of collision frequency loss in the characteristic equation results in the conversion of dominant mode to first higher order mode as the bias field is increased. GPF analysis for ridged waveguide configuration at 250 GHz results in optimum value of GPF when magnetoplasma semiconductor is in a superstrate position with low permittivity dielectric substrate below a half rigde height.
