Abstract
This paper presents an investigation of the magnetostatic modes in a semi‐infinite slab of hexagonal planar ferrite which is magnetized along the face of the slab. Unlike the case of isotropic ferrites, the slab of planar ferrite supports volume modes even in the absence of the variation of rf field along the dc magnetization. Surface modes are allowed so long as the anisotropy field is smaller than the saturation magnetization. The surface modes cease to exist when the anisotropy field exceeds the saturation magnetization, but the introduction of a perfect conductor on one side of the slab allows the propagation of a band of unidirectional surface waves which may be useful in device applications at relatively high frequencies.This publication has 11 references indexed in Scilit:
