Tunable Microwave Transversal Filters.

Abstract

This final report for the third year of contract AFOSR-80-0264 summarizes the results of a fundamental investigation of a viable technological realization of this goal through magnetostatic waves MSW propagating at microwave frequency in magnetically biased, liquid phase epitaxial films of yttrium iron garnet (YIG) grown on gadolinium gallium garnet (GGG). This technology has a number of advantages; low loss (greater than 30db/usec at xband), tunable by bias field to any center frequency (1-20GHz), long wavelengths (10-100 micrometers at any frequency), and finally a well understood and characterized wave phenomena (MSW) is utilized. The necessary non-recursive transversal filtering is achieved through multi-element transducer and/or the interaction of the MSW with periodic structures in or on the YIG film.
