Abstract

Numerical results obtained under the rigid-solid assumption are presented for compound arrays as a function of both parallel-to-plate wave-vector and frequency. Transmission minima arising from the interference between hole resonances interact with Wood anomalies. In addition, preliminary results on underwater ultrasound transmission measurements through a plate perforated with a rectangular hole array employing single point and synthetic aperture technique are presented.
