Theoretical and experimental work was directed toward the development of wedge transducer techniques suitable for the generation of broadband surface acoustic Love waves in the frequency range from 100 MHz to 500 MHz. Theoretical studies characterized wedge transduction and Love wave propagation characteristics. Bonding agents were identified which provided strong coupling of bulk shear waves to acoustic surface waves. Fused quartz and zinc oxide wedge transducers were used to excite surface waves in the VHF region. The propagation properties of Rayleigh waves on free surfaces and Rayleigh and Love waves on layered surfaces were investigated. Love and Rayleigh waves were guided on substrates of silicon using etched SiO2 waveguide structures. Author
