摘要：
We have derived new simple and concise six-port equivalent circuit models and their transfer matrices of an N-pair of interdigital transducers (IDT) for analyzing two-port surface-acoustic-wave (SAW) devices such as filters and resonators. The present models include various secondary effects such as electrical shorting and mass loading effect (MEL) and energy storage effect. Therefore, they can predict characteristics close to the actual performances of devices.
