Simulation of Surface Acoustic Wave Devices [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2004 The Mason crossed-field circuit model is generalized to simulate apodized interdigital transducers without channel division. The apodized transducer model is based on the transmission line model, and the artificial transformer with different voltage and current coupling ratios is used to independently obtain the transfer function and radiation ...
