Effect of the parallel reflecting surfaces of a transducer on the resulting pulse shape

Abstract
Calculations are made of the pulse shapes for sound waves reflected from a plane transducer. These show the effect of reflections from the two parallel surfaces and their relation to pulse width and transducer thickness. Illustrations are given for several representative combinations of samples and backing media, together with photographs of pulse shapes obtained experimentally. Subject Classification: [43]35.80; [43]85.40; [43]20.30.
