One-port magnetostatic wave resonator
暂无分享,去创建一个
A tunable one-port magnetostatic surface-wave resonator is formed in the 2 GHz to 4 GHz band by center feeding a periodic array of grooves etched in an epitaxial yttrium iron garnet film. Measured Q values of 550 are in reasonable agreement with theory.
