Electromagnetic interaction of arbitrary radial-dependent anisotropic spheres and improved invisibility for nonlinear-transformation-based cloaks

Cheng-Wei Qiu, Andrey Novitsky, Hua Ma +1

An analytical method of electromagnetic wave interactions with a general radially anisotropic cloak is established. It is able to deal with arbitrary parameters (${\epsilon }_r(r)$, ${\mu }_r(r)$…
