Theory of MSW transducers

In the present electrical equivalent circuits for multielement magnetostatic wave (MSW) transducers, for the cases of a transmission line and a two-terminal model, both models are extended to all three principal modes of MSW propagation. Computer programs have been obtained for the plotting of phase and amplitude response, as measured by commercial network analyzers. Attention is given to the basic assumptions, similarities, and differences, advantages, disadvantages and limitations of the two models. The useful range for these devices extends over 1-12 GHz.
