Abstract :
In this paper, an analysis for a separated-medium SAW device model is presented. A computer programs is built (according to perturbation theory) to determine the changes in the relative velocity and the attenuation of the SAW for different media and substrates. The effect of applying a DC voltage to the adjacent medium on SAW is investigated. The usage of this model is presented. Medium characteristics such as the mobility carriers and the concentration carriers are determined. The simulation results obtained from this model are discussed.
