N2 - Insertion loss and acoustic reflection for surface acoustic wave (SAW) unidirectional-interdigital transducers are expressed by scattering matrices with energy dissipation in a general form. In the case where circuit energy dissipation could be represented as a lumped resistance (or a conductance), loss and reflection of the transducers can be calculated. Furthermore, the dissipation matrix elements expressed by electrical reflection are proposed. These results are verified by experiments.
