Cloaking Using the Anisotropic Multilayer Sphere

Blog Article

We studied a Spherically Radially Anisotropic (SRA) multilayer sphere with sophie allport bee curtains an arbitrary number of layers.Within each layer permittivity components are different from each other in radial and tangential directions.Under the quasi-static approximation, we developed a more generalized mathematical model that can be used to calculate polarizability of the SRA multilayer sphere with any arbitrary number of layers.

Moreover, the functionality of the SRA multilayer sphere as a cloak click here has been investigated.It has been shown that by choosing a suitable contrast between components of the permittivity, the SRA multilayer sphere can achieve threshold required for invisibility cloaking.
