A metamaterial based on the design of Shin et al. [Phys. Rev. Lett. 102, 093903 (2009)] that allows independent control of its permeability and permittivity has been fabricated and experimentally characterised. It is comprised of an array of metallic cubic-shaped elements with faces that are connected only through six orthogonal spokes emanating from the centre. The permeability is tailored through appropriate patterning of the faces, thereby controlling the propagation of eddy currents around the cubic elements while permittivity may be controlled by the thickness and dielectric constant of the inter-cube spacers.
