Abstract

The normal modes of a transversely magnetized ferrite cylindrical waveguide are found using a coupled mode approach. The bias yoke generates an electrically rotatable four-pole transverse magnetic field in the ferrite producing birefringence phase shift. The changes of polarization state of the electromagnetic wave at the output of the guide sections of different lengths are investigated and applied to develop a rotatable half-plate section useful for phase shifter design.
