title: Theoretical and experimental evaluation of a two-dimensional composite matrix array.
abstract: A theoretical and experimental performance appraisal of a two-dimensional, ceramic-epoxy composite matrix array employing 1-3 connectivity is presented. The linear systems approach is used for temporal and spatial simulation of array performance, with specific regard to three-dimensional synthetic aperture imaging in a fluid load medium. Manufacture and experimental evaluation of a prototype array structure, operating at 1.2 MHz and comprising 100 elements arranged as a 10 by 10 matrix, is described. Close agreement between theory and experiment is obtained, providing a clear indication that the low crosstalk, uniformity, and wideband characteristics of composite array elements offer excellent prospects for such imaging applications.
