Abstract

In this article we study helical inclusions of a certain shape (called the “optimal shape”), such that the electric, magnetic, and magneto-electric polarizabilities are equal, and discuss unusual refractive and absorptive properties of artificial chiral materials based on such inclusions. We propose a new method of analytical calculation of resonant susceptibility of non-canonical, but true three-dimensional spirals. This method takes into account spiral trajectories and effective concentration of conduction electrons.
