Abstract

High-performance, high-frequency interdigital transducers (IDTs) for the generation of surface acoustic waves (SAWs) on GaAs substrates, where the metal fingers are embedded in the substrate are investigated. The findings show that the acoustic reflections and the scattering of the surface modes into the substrate become considerably reduced in these transducers, leading to an increased output power.
