Surface Acoustic Wave Devices Using Lithium Niobate on Silicon Carbide
IEEE transactions on microwave theory and techniques, 2020 This work demonstrates a group of shear horizontal (SH0) mode resonators and filters using lithium niobate (LiNbO3) thin films on silicon carbide (SiC). The single-crystalline X-cut LiNbO3 thin films on 4H-SiC substrates have been prepared by ion-slicing

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 ...
