Negative refraction from balanced quasi-planar chiral inclusions

This work proposes a quasi-planar chiral resonator suitable for the design of negative refraction index metamaterials. It is presented as an analytical model to determine the metamaterial polarizabilities, which is also the basis of a further study of the viability of negative refraction in chiral and racemic arrangements of inclusions made up with the proposed quasi-planar chiral resonator. The present analysis is expected to pave the way for the design and building feasible negative refractive index metamaterials whose inclusions can be manufactured by means of standard photo-etching techniques.
