Abstract
This article presents an accurate, approximate analysis for the receiv er voltage in a geometry with bounded acoustic beams reflected from fl uid-loaded structures. The relationship between reflection coefficient poles and transducer voltage minima is calculated and discussed. A se ries of precision experiments on a uniform, homogeneous plate is shown to validate the calculation. These results have significance for mate rial property extraction from reflection measurements on fluid-loaded structures.
