On the application of periodic electrical boundary conditions as a means of achieving tunable RF SAW devices
Résumé
A single port SAW resonator is designed, due to its simplicity, a method for extracting the reflection coefficient of its mirrors is developed. Through this method, the mirror response as a function of different
periodic electrical boundary conditions is studied and tunable Bragg band gaps as well as bands of high reflection coefficient due to local resonances of the mirror electrodes are shown.
