Infrared plasmons propagate through a hyperbolic nodal metal
Infrared plasmons propagate through a hyperbolic nodal metal
Metals are canonical plasmonic media at infrared and optical wavelengths, allowing one to guide and manipulate light at the nanoscale. A special form of optical waveguiding is afforded by highly anisotropic crystals revealing the opposite signs of the dielectric functions along orthogonal directions. These media are classified as hyperbolic and …
