MSW Transducers
Abstract
This report summarizes research performed at RADC/EEA on magnetostatic wave transducers. Using the theory presented here, MSW delay line characteristics such as insertion loss, phase, time delay, and input impedance may be computed as a function of frequency. The delay line is made up of identical input and output transducers with a ferrite delay medium. Input parameters are: magnetic biasing field, transducer geometry, YIG parameters, and ground plan spacings. The theory developed accurately predicts the behavior of single element MSW transducers on YIG. It predicts the behavior of multielement transducers that are weakly coupled to the YIG when individual transducer of elements are narrow compared to interelement wavelengths. The report also includes the following : A review of basic MSW phenomena; a detailed MSW transducer analysis; a description of MSW computer programs with examples; a summary of transducer models; a transducer apodization equation that agrees well with experiment; and, a detailed analysis of the back reaction of a strongly coupled MSW onto the generating current distribution, in single strip.
