Physical Review B, 1994•APSWe analyze the two-dimensional potential around a coated cylinder placed in a nonuniform
field. In two special cases the system behaves as if the core of the cylinder were enlarged
and the shell absent. These are when the shell dielectric constant is the negative of either
the core dielectric constant or the matrix dielectric constant. When the shell dielectric
constant has a small imaginary part, the field can exhibit large fluctuations which remain
localized near the surface of the coated cylinder.

Abstract
We analyze the two-dimensional potential around a coated cylinder placed in a nonuniform field. In two special cases the system behaves as if the core of the cylinder were enlarged and the shell absent. These are when the shell dielectric constant is the negative of either the core dielectric constant or the matrix dielectric constant. When the shell dielectric constant has a small imaginary part, the field can exhibit large fluctuations which remain localized near the surface of the coated cylinder.
