Dual-band optical negative index metamaterial based on hexagonal arrays of triangular nanoholes in metal–dielectric films

Multi-band near-field radiative heat transfer between two anisotropic fishnet metamaterials

“…When acting as a function devices, this planar metamaterial is easier for illumination and detection compared with that of conventional metamaterial, such as wires and split rings [19]. In addition, multiple magnetic responses are supported by the FMM due to the excitation of the surface plasmon polaritons (SPPs) propagating on the outer surface of metal (external SPPs) and along the inner metaldielectric interface (internal SPPs) [39][40][41][42], which should bring new characteristics to the near-field radiative heat transfer. In this paper, we investigate the role of multiple magnetic responses on the near-field radiative heat transfer between two FMMs by means of the fluctuational electrodynamics.…”
