PHASE SHIFT IN GaAs MAGNETOPLASMA RIDGED PARALLEL-PLATE WAVEGUIDES

摘要

The nonreciprocal properties of lossy GaAs magneto-plasma ridged parallel-plate waveguides are assessed at 250 GHz using a gyroelectric performance factor The optimum phase shift for a two-layer structure is predicted when the magnetoplasma semiconductor is in a superstate position with a low-permittivity dielectric substrate below a half-height ridge. This arrangement exhibits TEM to (TM){sub}(01) mode conversion.
