Electromagnetic shielding effects using chiral and other complex materials

The present study focuses on the attenuation analysis of spherical shell structures that are made of complex materials. An analysis will be presented which calculates the electric and magnetic fields within spherically layered structures in the quasistatic limit, in other words the wavelength of the field has to be smaller than the diameter of the shell. Due to the magnetoelectric coupling which is inherent in chiral and other novel complex materials, the electric and magnetic field problems cannot be treated separately. The newly developed six-vector formalism is used in the analysis. Numerical results are shown for the shielding effectivity of a chiral shell.
