We consider the scattering of time harmonic electromagnetic plane waves by a bounded, inhomogeneous, anisotropic dielectric medium and show that under certain assumptions a lower bound on the norm ofâ€¦ (More)

We continue the development of high-order accurate thin layer approximations for time-domain electromagnetics and focus in this paper on thin transmission layers. The thin transmission layerâ€¦ (More)

We analyze the well-posedness and stability properties of a parameter dependent problem that models the reflection and transmission of electromagnetic waves at a thin and rapidly oscillatingâ€¦ (More)

We consider the three dimensional electromagnetic inverse scattering problem of determining information about a target buried in a known inhomogeneous medium from a knowledge of the electric andâ€¦ (More)

Diffusion magnetic resonance imaging provides a measure of the average distance travelled by water molecules in a medium and can give useful information on cellular structure and structural changeâ€¦ (More)

In this paper, we consider the transmission eigenvalue problem for Maxwellâ€™s equations corresponding to non-magnetic inhomogeneities with contrast in electric permittivity that changes sign insideâ€¦ (More)

This paper is dedicated to the construction and analysis of so-called Generalized Impedance Boundary Conditions (GIBCs) for electromagnetic scattering problems from imperfect conductors with smoothâ€¦ (More)

We consider a wave equation with fractional-order dissipative terms modeling viscothermal losses on the lateral walls of a duct, namely theWebsterâ€“Lokshin model. Diffusive representations ofâ€¦ (More)

We consider the inverse scattering problem for a cavity that is bounded by a penetrable anisotropic inhomogeneous medium of compact support and seek to determine the shape of the cavity from internalâ€¦ (More)
