Thermostability of obliquely magnetized magnetostatic wave straight edge resonators

The frequency shift due to temperature variation in the microwave response of a magnetostatic forward volume wave YIG straight edge resonator in a band-stop configuration filter has been measured. In particular, the effect of the angular variation /spl theta//sub e/ of the dc magnetic bias field H/sub e/ with respect to the film plane on the temperature frequency shift has been experimentally tested, and it has been demonstrated that thermostability improvement can be obtained as a function of /spl theta//sub e/. Moreover, a good agreement between theoretical expectations and experimental findings has been obtained.
