Cloaking using anisotropic multilayer circular cylinder

In this article, we study a homogenization model for cloaking applications. In the given model, we consider an isotropic inner layer, which iscoated with a multilayer anisotropic circular cylinder. We describe the electrostatic response of a polarly radially anisotropic (PRA) multilayercircular cylinder. It consists of different components of permittivity in radial and tangential directions for each layer. We have shown themathematical derivation of the polarizability and effective permittivity of a PRA multilayer circular cylinder. Moreover, we demonstrate thecloaking behavior using a PRA multilayer circular cylinder. Meanwhile, we test our formation with advanced computational approaches.During our numerical test, we have investigated the numerical results of the polarizability of a PRA multilayer circular cylinder. We employan inner cloak surrounded by a multilayer anisotropic circular cylinder. However, for an ideal cloak, the contrast between the permittivityparameters approaches infinity.
