FEM analysis of wavelength effects in piezoelectric substrate

In this paper, we discussed simulation of several annular surface acoustic wave (A-SAW) devices using various wavelengths to identify its effects on the focusing properties and to analyze the propagation of Rayleigh waves in piezoelectric substrate. By choosing Y-cut Z propagating Lithium Niobate as...
