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. © 2008 American Institute of Physics.
