Single-mode subwavelength waveguides with wire metamaterials
arXiv:1307.4216 · doi:10.1063/1.4824478
Abstract
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.
