Abstract :
Nonreciprocal propagation in parallel plate, magnetoplasma waveguide is restricted to transverse magnetic (TM) modes when the waveguide cross-section is nonsymmetrical. The analysis of this canonical structure is extended here by including collision frequency loss in the characteristic equation and by studying mode propagation in the extraordinary wave resonance region. Conversion between the dominant and first higher order mode is observed as the bias field is increased through resonance. Field plots are included to illustrate this effect.
