Abstract

The purpose of this paper is to provide a new analytical model from which the elementary electroacoustic response and directivity pattern of 1D piezocomposite arrays are simultaneously predicted. The approach is based on the propagation theory in multi-layers structures. The model has been used for simulating a complete 1D array. A test device has been constructed and characterized through measurements of displacement and angular directivity. Experimental results are presented and compared with theory.
