Description

The results presented here are part of a study of the interaction between an electro-mechanical transducer plate element and wavelengths in the test structure that are comparable to the plate dimensions. The steady time-harmonic problem is reduced to a system of singular integral equations for determining the tractions generated at the interface between the plate and half-space where a thin viscous couplant is applied. This system is solved numerically for various values of couplant viscosity and incident wavelength. Graphical results for interface tractions and reflected power are presented.
