Here, we numerically demonstrate electromagnetic focusing using a metamaterial formed by nonconnected crossed metallic wires. It is shown that the focusing effect is a consequence of the phenomenon of broadband all-angle negative refraction that occurs at an interface between the nonlocal material and a regular dielectric. We describe our ongoing investigation on the focusing properties of the crossed wires lens, highlighting new possibilities
