摘要：

A phenomenological unloaded Q-factor (Qu) theory has been derived for all the three kinds of magnetostatic-wave straight-edge resonators (MSW-SERs), i.e., forward volume wave (MSFVW), backward volume wave (MSBVW), and surface wave (MSSW). It turns out that the Qu values of MSW-SERs are very close to that of the uniform precession mode with the exception of MSSW-SERs and MSBVW-SERs operating at frequencies below 3 GHz. The experimental responses on MSFVW-SERs are in good agreement with those predicted by the present theory.
