title: FEM/BEM analysis of a generalized periodic array.
abstract: 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 proposes a mixed FEM/BEM numerical model for the simulation of a periodic array of metallic electrodes, the elementary cell of which can be as complex as necessary: it can contain several electrodes, connected to active ports, or short-circuited, or floating.
