In this work, we numerically demonstrate electromagnetic focusing using a spatially dispersive metamaterial. Based on the phenomenon of broadband all-angle negative refraction by a crossed wire mesh, it is demonstrated that a flat slab of the metamaterial enables partial focusing of p-polarized electromagnetic radiation. The reported results are supported by full wave simulations and by analytical calculations based on homogenization theory.
