Abstract
We study the conditions for plasmon canalization over ultrathin metasurfaces, including dispersion, polarization and energy transport phenomena. Our analysis reveals that plasmon canalization can be ideally implemented by significantly increasing either the imaginary or the real part of one diagonal component of the metasurface conductivity tensor, which enables lossy metamaterial resonances on these structures. We then put forward a novel infrared platform based on nanostructured black phosphorus to implement this concept, exploiting the extreme intrinsic anisotropy of this 2D material, boosting canalization beyond what isotropic materials like graphene can offer, and enabling exciting possibilities for integrated and reconfigurable nano-waveguides, communication systems, hyperlenses and imaging applications.
