    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 superstrate position with a low-permittivity dielectric substrate below a half-height ridge. This arrangement exhibits TEM to TM01 mode conversion. © 2005 Wiley Periodicals, Inc.
