Magnetostatic Wave Transducers with Variable Coupling,

Abstract

Transducer theory for magnetostatic waves in saturated ferrites is extended to include variable coupling. A gap is introduced between transducer and ferrite to adjust the coupling between electromagnetic driving structure and magnetostatic waves. Expressions are developed for the radiation resistance of normal modes of a truncated infinite array and for independent transducer conducting strips of a finite array, as a function of liftoff, for grating and meander transducers. This technology has application in microwave signal processing systems. (Author)
