Theoretical studies on a (FGPM) system with Gaussian profile for a zero TCD SAW devices
We investigate the propagation of surface wave in a functionally graded piezoelectric material layer ZnO/AlN/ZnO on α-Al2O3 substrate in this study. The influence of buffer layer thickness on the temperature coefficient of delay (TCD) is studied. The stiffness matrix method (SMM) and the ordinary di...
