Description
Metasurfaces, the two-dimensional (2D) counterpart of metamaterials, have recently attracted a great deal of attention due to their amazing properties, including negative refraction, hyperbolic dispersion, and manipulation of the evanescent spectrum. In this work, a theory model is proposed for the near field radiative heat transfer (NFRHT) between two nanoparticles in the presence of an anisotropic metasurface. Specifically, the metasurface is modeled as an array of graphene strips (GS), which is an ideal platform to implement any metasurface topology, ranging from isotropic to hyperbolic propagation. The NFRHT between two nanoparticles are significantly amplified when they are placed in the proximity of the GS, and regulated over several orders of magnitude. In this configuration, the anisotropic surface plasmon polaritons (SPPs) supported by the GS are excited and provide a new channel for the near-field …
