Abstract :
The authors propose a type of magnetostatic wave resonator using a yttrium iron garnet (YIG) film with circular metal strips. The characteristics of these have been analyzed by making use of the mode-matching technique. The magnetic potential distribution outside of the microstrip disk was evaluated numerically with high concentration of magnetostatic wave energy, and a mode chart with various resonator dimensions is presented. Experiments were carried out using 20- mu m-thick YIG film with a 6-mm-diameter microstrip disk. Typical resonance characteristics show loaded Q of 340, an average insertion loss of 15 dB, and a dynamic range of 25 dB.<>
