Magnetostatic wave transducers
Abstract
A technology for analog, real time microwave signal processing at GHz frequencies (1-18 GHz) is presented. It utilizes slow magnetostatic waves (MSW) propagating in magnetically biased yttrium iron garnet (YIG) films. The MSW transducer was designed to create efficient energy transduction between the electromagnetic input excitation and the excited MSW launched in the YIG film, and also to achieve controlled bandpass shaping by using multiple element transducer arrays. The first successful study and modeling of both MSSW and MSFVW transducers for multielement devices were presented as well as the first impedance characterization at the driving point for these same transducers.
