摘要：

An accurate simulation tool has been developed to meet the stringent requirements for broadband surface-acoustic-wave (SAW) filters. The model takes into account surface wave diffraction and refraction, quasi-two-dimensional (2-D) static charge distribution, metal resistance and external load impedances. The angular spectrum of waves (ASoW) formalism is interpreted in such a way as to render possible the simultaneous description of all effects mentioned. A sample of the results is given for the potential distribution.
