Symmetric wave corrections to the line driven, fluid loaded, thin elastic plate

The effect of coupling between in-plane (symmetric wave) plate vibrations and the acoustic field are investigated in the context of thin plate theory. Comparisons are made of the reflection and transmission coefficients with the results of three-dimensional elasticity and the fluid loaded dispersion curves are considered. The response of a line driven, fluid loaded, air-backed thin plate is calculated and it is shown that symmetric wave corrections can give contributions at leading order, for certain ranges of angle or frequency.
