FEM/BEM Analysis of a Generalized Periodic Array

Recent developments in wide bandwidth SAW filter design led to the use of complex electroacoustic cells, such as the Hanma-Hunsinger cell. For this kind of structure, it is not sufficient to use only a single electrode periodic FEM/BEM model to derive the P-matrix parameters. The present paper propo...
