Abstract
Hypersonic surface acoustic wave (SAW) propagation was experimentally studied by laser Doppler vibrometry. The SAW was measured along different regions of nanocrystalline silicon devices at excitation frequencies from 2-2.3 GHz. The data reveals wavelength variations, phase velocity differences and acoustic impedance mismatches which contribute to the dissipation of mechanical energy.
