Magnetostatic Surface Wave Transducer Design

摘要

Magnetostatic surface wave (MSSW) transducer theory is extended and generalized. A Fourier transform relation is established between MSSW field amplitudes and transducer spatial current distribution. Advanced design equations are presented including: radiation resistance for periodic meander and grating transducers; spatial harmonic amplitudes and radiation resistance for uniform and nonuniform current distribution models; and radiation resistance for apodized transducers.
