Designing a Negligible Reflection Coefficient for a Uniform Panel with Compliant Layer

Abstract

The use of a mechanical compliant layer to achieve a negligible reflection coefficient atop a uniform panel facing a fluid and backed by vacuum is investigated. The material properties of the compliant layer that need to be maintained to achieve the set goal are specified in terms of the surface stiffness and the loss factor of the layer. A necessary relationship between these quantities emerges. Keywords: Compliant layer, Reflection coefficients.
