Abstract:Piezoelectric materials have nonlinear effects that can be used in 5G and IoT technologies. However, since most nonlinear problems in this area do not have analytic solutions, FEM simulations are an essential design tool. In this study, we have developed a stress-charge formulation for non-linear piezoelectric materials compatible with commonly used simulation tools in industry and research. FEM simulation results for AlN with three nonlinear phenomena are presented: variation of effective electrical permittiv… Show more
