Magnetostatic Wave Dispersion Relations,
Abstract
The results presented here summarize and expand earlier results for magnetostatic wave dispersion relations and for magnetostatic wave oscillators. In what follows is presented the dispersion relations for generalized volume waves and generalized surface waves for a thin YIG (Yttrium Iron Garnet) film bounded by two ground planes. Computer produced curves for volume waves and surface waves are presented. In particular, for volume waves in the plane phase=O there is indicated an application to nondispersive electronically tunable time delay elements. Also presented is a comparison between a theoretically obtained dispersion curve for surface waves and one obtained by a computer controlled experiment. There is also presented an analysis for magnetostatic wave oscillator frequencies for surface waves and for forward and backward volume waves. The authors take into account the possibility of obtaining multiple modes for volume waves. Comparisons are made between the curves obtained from theoretical considerations and those obtained experimentally at RADC, for surface waves and forward and backward volume waves.
