Abstract
The dominant frequency of a solidly mounted resonator (100/280/300/400) is substantially increased by reducing the thickness of each layer of each Bragg acoustic reflector (112/160/224/274) to have a thickness than is substantially equal to one-quarter of the wavelength of a frequency that is a higher harmonic resonant frequency of the fundamental resonant frequency of the solidly mounted resonator (100/280/300/400).
