Single-mode subwavelength waveguides with wire metamaterials

Belov, Pavel; Dubrovka, Rostislav; Iorsh, Ivan; Yagupov, Ilya; Kivshar, Yuri


We study the eigenmodes of a slab of a wire metamaterial and demonstrate that such a waveguiding structure supports deep-subwavelength propagating modes exhibiting properties of a single-mode waveguide at any fixed frequency below the plasma frequency of metal wires. We compare our analytical results with the dispersion relations extracted from the experimental measurements.
