Whispering gallery modes for elastic waves in disk resonators

The resonant modes of elastic waves in disk resonators are computationally studied with the finite difference time domain method. Different materials examined for the disk such as platinum and silicon. The effect of a glass substrate is also important especially in the case of silicon disks because of the similarity of sound velocities and mass densities between the two materials. The possibility of using those structures as sensors is also considered. Copyright 2011 Author(s). This article is distributed under a Creative Commons Attribution 3.0 Unported License.
