Radiophysics and Quantum Electronics Aims and scope

Abstract

The sound radiated from an electrically excited piezoelectric plate is computed. Voltage distributions obtainable from an array of finite sized electrodes are used to examine the possibility of actively suppressing sound radiated at particular spatial wavenumbers. An application to canceling the reflection of a plane wave at oblique incidence is presented. The results presented here can also be found in Barbone & Braga (1992).
