Following our recent theoretical studies M. G. Silveirinha and C. A. Fernandes, Phys. Rev. B 78, 033108 2008, it is experimentally verified that an array of crossed metallic wires may behave as a nonresonant material with extremely large index of refraction at microwaves and may enable the realization of ultrasubwavelength waveguides.
