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 30dbusec 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 andor the interaction of the MSW with periodic structures in or on the YIG film.
