Estimates for the
Effect of Small Electromagnetic Inhomogeneities and
their Relevance to Approximate Cloaking
Professor

Abstract:
I shall provide a review of work carried out over
the last 10 years or so, the focus of which has been
to very precisely assess the field perturbations
caused by the presence of small electromagnetic
inhomogeneities. Special attention will be devoted
to the question of the independence of such
estimates of the material properties of the
inhomogeneities.
One principal reason for the interest in material
independent estimates is that they provide a very
effective tool for the assessment of the level of
"invisibility" associated with natural families of "nondegenerate,
approximate" cloaks.
