Peculiarities in the Dielectric Response of Negative-Permittivity Scatterers

By Ari Sihvola
Progress In Electromagnetics Research, Vol. 66, 191-198, 2006


This study analyzes polarizability properties of spherically layered small inclusions that possess negative permittivity. Conditions for invisibility to external electric fields are derived. The complementary principle for two-dimensional scatterers is used to derive special properties of self-complementary inclusions. A singular behavior between the limits of invisibility and infinite response is underlined for a hollow circular shell. A similar,although not as drastic,phenomenon is shown to take place for the three-dimensional hollow sphere.
