In this paper we study both theoretically and experimentally the exotic waveguiding properties of ultra-compact metamaterials formed by crossed metallic wires, revealing their superior bandwidth, tolerance to absorption and reduced physical size. In particular, the proposed structured waveguide supports highly confined plasmons with entangled dispersion. The studied waveguide supports such waves over a much wider range of frequencies as compared to other known solutions based on spoof surface plasmons or semiconductor plasmonic-type waveguides.
