Building elements of a volumetric metamaterial

This paper presents the results of an investigation into a combination of electric and magnetic planar resonators in order to design the building element of a volumetric metamaterial showing simultaneously negative electric polarizability and magnetic polarizability under irradiation by an electromagnetic wave. The magnetic element is a split ring resonator, and the electric element is an electric dipole terminated by an inductor. The response of the single resonant particle is strongly anisotropic. Proper spatial arrangement of these particles can make the response isotropic. The possibility of obtaining a non-bianisotropic response is taken into account.
