Abstract Light waves are too short and ordinary sound waves generally too long to permit experimental work on diffraction and scattering by a single small obstacle. An opportunity for such work however is presented in the case of ultrasonic waves.This paper describes an experimental investigation on...
A study of the diffraction and scattering of a transverse electric X-wave by conducting bodies is presented based on the timedomain, uniform theory of diffraction method and the pulsed plane wave representation of an X-wave. The latter allows the calculation of the diffraction and scattering of ...

Insertion loss and acoustic reflection for surface acoustic wave (SAW) unidirectional-interdigital transducers are expressed by scattering matrices with energy dissipation in a general form. In the case where circuit energy dissipation could be represented as a lumped resistance (or a conductance), loss...

The experimental observation of a three-dimensional diffraction phenomenon at a 90 degrees Bragg reflection is reported and discussed. A refined experimental technique for the direct observation and accurate measurement of scattered intensity profiles in the vicinity of a 90 degrees Bragg reflection was ...
reflection lobes: a directional specularbeam with superimposed multi-directional lobes. The latter ones are the result of diffuse reflection, which can arise from multiple surface reflections in a rough, facetted surface as well as diffraction scattering from the microtopography of the top surface.[5...
the ratio of the radiant flux reflected by a body to the radiant flux incident on it. The concept of an amplitude reflection coefficient, that is, the ratio of the amplitudes of the reflected and incident waves, is sometimes used —for example, for radio waves. In general, the reflection ...
