O. Yu. Shmaliy, EIGENVIBRATIONS OF A CONVEX PIEZOELECTRIC PLATE WITH ELLIPSOID SURFACE, Proc. of CAOL 2003, Sept. 16-20, Alushta, Crimea, Ukraine. – P. 223-226.
This report addresses an analysis of the eigenfrequencies of the convex piezoelectric resonator of the ellipsoid shape with arbitrary orientation of the ellipsoid axes with respect to the self-axes of the piezoelectric crystal. As an essential result of the studies, we show that the frequency spectrum of a resonator strongly depends on anisotropy of the piezoelectric surface. It needs to be remarked that such anisotropy involves additional parameters (unlike the case of spherical model of a resonator) to adjust spectrum of the resonator and, thus, the model is more flexible. On the other hand, the additional parameters make possible achieving much more optimized spectral performance of a resonator. |
