Magnetostatic wave coupled straight edge resonators have been experimentally tested by means of a waveguide ferromagnetic resonance experiment to check their potential as microwave coupled filters. Few dB ripples and tens of MHi bandwidths have been obtained for configurations in the range jY4-to X-coupling.

An analysis of the signal reflections originating at the garnet film ends and of the triple transit between the microstrip transducers in magnetostatic volume wave delay lines has been performed. The influence of those effects on the band shape and on the insertion loss of magnetostatic wave devices has been inferred and compared with experimental results. In this framework, the possible utilization of the reflections for filterbank applications is also proposed.
