Scattering of plane harmonic SH waves by multiple inclusions

Scattering of time-harmonic electromagnetic plane waves by perfectly conducting diffraction gratings

Consider the scattering of time-harmonic electromagnetic plane waves by a doubly periodic surface in R 3. The medium above the surface is supposed to be homogeneous and isotropic with a constant dielectric coefficient, while the material below is perfectly conducting. This paper is concerned with the existence of quasiperiodic solutions for any frequency. Based on an equivalent variational form...

Scattering of Elastic Waves by Inclusions with Thin Interface Layers

Elastic waves are scattered by an elastic inclusion. The interface between the inclusion and the surrounding material is imperfect: the discontinuity in the displacement (traction) vector across the interface is taken to be proportional to the average of the traction (displacement) vectors on the two sides of the interface. Uniqueness theorems are obtained, and boundary integral equations over ...

Multiple scattering of flexural waves by random configurations of inclusions in thin plates

Article history: Received 19 May 2010 Received in revised form 15 September 2010 Accepted 5 October 2010 Available online 13 October 2010 Flexural waves are scattered by inclusions in a thin plate. For a single inclusion of arbitrary shape, reciprocity relations are obtained connecting coefficients in circular multipole expansions. Then, a formula for the effective wavenumber in a random arrang...

Scattering of plane elastic waves by three-dimensional diffraction gratings

Scattering by Inclusions ∗

Time-harmonic waves are scattered by obstacles, through which waves can also travel. Various examples from acoustics, elastodynamics and electromagnetics are discussed, including imperfect interfaces, chiral materials and wood. The paper gives a very subjective overview but with emphasis on the contributions and influence of Ralph Kleinman.
