Abstract
Insertion loss and acoustic reflection for surface acoustic wave (SAW) unidirectional-interdigital transducers are expressed by scattering m atrices with energy dissipation in a general form. In the case where c ircuit energy dissipation could be represented as a lumped resistance (or a conductance), loss and reflection of the transducers can be calc ulated. Furthermore, the dissipation matrix elements expressed by elec trical reflection are proposed. These results are verified by experime nts.
