Isotropic and Homogeneous Behavior of Chiral Media Based on Periodical Inclusions of Cranks

Isotropic chiral materials at microwave frequency are usually obtained by distributing, as random as possible, elements of chiral symmetry in a host medium. Here we propose a new manufacturing technique based on the precise location of same handedness cranks in a periodical configuration. By this method electromagnetic active media are produced with homogeneous, isotropic and reciprocal behavior for the microwave frequency range. These materials also present some fabrication advantages and new parameters for material design.
