A Surface Acoustic Wave (SAW) is a wave propagating along the surface of an elastic substrate with an amplitude that typically decays exponentially with depth into the substrate. To generate SAWs, an Interdigital Transducer (IDT) is used which can also act as a source or receiver of SAW. The present paper attempts to review the latest research work done in the last twenty years in design and co...
Geoacoustic inversion requires a generic knowledge of the frequency-dependence of compressional wave properties in marine sediments, the nature of which is still under debate. The use of in situ probes to measure sediment acoustic properties introduces a number of experimental difficulties that must be overcome. To this end, a series of wellconstrained in situ acoustic transmission experiments ...
Surface acoustic wave (SAW) devices based on Rayleigh wave, shear wave, love wave, acoustic plate mode (APM) wave and flexural plate wave have been explored for sensors, actuators and telecommunication applications. An interdigital transducer (IDT) is a metallic comb-like structure fabricated over piezoelectric substrate. SAWs are generated over the substrate by applying electrical signal to th...
