“…The influence of the gap depends on sample manufacturing and can be overcome, for instance, by locating the chiral particles in non-conducting spheres [8], since the multiple air gaps between the spheres are part of the sample, or by using an elastic material as dielectric host for distributing the chiral particles [12].…”

A chiral medium constituted by a two-dimensional lattice of eight cranks of the same handedness is studied and found that it exhibits a huge electromagnetic activity, circular dichroism, and negative refraction index. Using a free-wave experimental setup and numerical simulations, the transmission and reflection coefficients for a thin slab of such metamaterials were determined, and the effective values for the refractive index, electric permittivity, magnetic permeability, and chirality parameter were calculated. The obtained results by means of the simulation agree quite well with the ones calculated from the experimental measurements.Index Terms-Chiral media, materials science and technology, metamaterials, microwave measurements.

“…In 2009, David et al proposed their application in electromagnetic absorbers [5] and, in 2010, Kopyt et al studied the electromagnetic behavior of such structure implemented with dielectrics (polymers), in order to check whether their structural chirality translates into chiral electromagnetic behavior (bianisotropy) [1], with negative results. It is worth noticing that they characterized a single layer of the structure: that means the result is not geometrically chiral in the 3D space, so no bi-anisotropic behavior should have been expected [6], [7].…”
