Translated title:
Scattering of electromagnetic waves by an orthotropic medium
Summary:
In this dissertation we will consider the scattering of electromagnetic waves
by a penetrable orthotropic in-homogeneity imbedded in a homogeneous
background. We will confine ourselves to the scalar case that corresponds to
the scattering of electromagnetic waves by an orthotropic infinite cylinder.
The direct scattering problem is modeled by a transmission problem for the
Helmholtz equation outside the scatterer and an equation with non constant
coefficients inside the scatterer. Then, we will concider the inverse
scattering problem for an inhomogenous orthotropic medium. The inverse problem
we shall consider is to determine the support of the orthotropic inhomogeneity
given the far field pattern of the scattered field for many incident directions.
