Magnetostatic Forward Volume Wave Straight Edge Resonators

The preformance of Magnetostatic Forward Volume Wave Straight Edge Resonators (MSFVW-SER) is presented. The resonator uses a rectangular YIG film to propagate Magnetostatic forward volume waves where the straight edges serve as reflectors. The interference of width mode resonances with the main resonance reported in the MSSW-SER is not observed in the MSFVW-SER. As a result, high-Q tunable microwave resonators with a tuning range from 1-20 GHz, insertion loss less than 8 dB and spurious rejection better than 10 dB have been designed and fabricated.
