โœฆ Synopsis

In this paper, we consider the scattering properties of a dielectric perturbed halfspace situated over a perfectly conducting plane P. We first analyze the influence of a short range perturbation of the physical properties (dielectric and magnetic) of the medium on electromagnetic fields, then we investigate the case when the conducting plane is replaced by an electromagnetic grating, for a suitable polarization of the fields. In these two situations, we give an estimate for the decay of local energy.

This paper is concerned with the inverse medium scattering problem in a perturbed, layered, half-space, which is a problem related to the seismologial investigation of inclusions inside the earth's crust. A wave penetrable object is located in a layer where the refraction index is different from the

We consider the self-adjoint operator governing the propagation of elastic waves in a perturbed isotropic half-space (perturbation with compact support of a homogeneous isotropic half-space) with a free boundary condition. We propose a method to obtain, numerical values included, a complete set of g

In this case, the asymptotic expansion of the resolvent at the origin has logarithmic terms. This prop

## The problem of a transient, transverse electromagnetic wave incident on a non-homogeneous half space is considered. Solutions are obtained by both the Laplace transform technique (LT) and the method of characteristics (MOC). The former method yields an infinite number of exact solutions in closed
