Using a multi-layered transducer model to estimate the properties of paraffin wax deposited on steel.

Abstract

When using ultrasound for detecting low impedance materials on the surface of high impedance materials, a major challenge is the contrast difference between the strong reverberations from the high impedance material and the weak echoes received from the low impedance material. The purpose of this work is to present the theoretical and experimental… (More)
