Shielding Effect Analysis on Layered Chiral and Dielectric Spheres

This paper deals with a theoretical study of chiral and dielectric media. Numerical results for polarizabilities have been investigated for chiral-chiral, chiral-dielectric, dielectric-chiral and dielectric-dielectric configuration. We have also discussed the effect of permittivity change on electric polarizaibility, magnetic polarizability and cross polarizabilities. Our aim is to give a comprehensive analysis of shielding effectiveness for different configurations of layered bi-isotropic spheres. Our findings include the diamagnetic character of chiral sphere. We present shielding effects as a function of material parameters: permittivity, permeability, and chirality. Results illustrate these effective parameters influence polarizabilities and on shielding effectiveness.
