Zero-index and hyperbolic metacavities: fundamentals and applications
TL;DR: In this article, a classification and implementation of zero-index and hyperbolic metamaterials for constructing the novel optical resonant cavities (ORCs) is presented, including the geometry-invariance, homogeneous/inhomogeneous field distribution, and topological protection.

Polariton topological transition effects on radiative heat transfer
TL;DR: In this paper, the authors studied the near field radiative heat transfer (NFRHT) between two twisted hyperbolic bilayer anisotropy materials, where the topological transitions of the surface state at a special angle [from open (hyperbolic) to closed (elliptical) contours] were investigated.

Optimized Colossal Near-Field Thermal Radiation Enabled by Manipulating Coupled Plasmon Polariton Geometry.
TL;DR: In this paper, a supported multilayer graphene structure was proposed to improve the state of the art with a ∼ 1129 fold-enhancement at a gap distance of ∼ 55 nm, where the plasmon polaritons at mid and far-infrared frequencies allowed for near-unity photon tunneling across a broad swath of k-space.

Near-field radiative heat transfer in hyperbolic materials
TL;DR: In this paper , the basic physics of near-field radiative heat transfer (NFRHT) for hyperbolic isof-frequency contours have been discussed. And the key challenges and opportunities of the NFRHT in terms of fundamental physics, experimental validations, and potential applications are outlined and discussed.

Enhanced Near-Field Radiative Heat Transfer between Graphene/hBN Systems.
TL;DR: In this paper , the NFRHT between graphene/hexagonal boron nitride (hBN) systems with a gap space of ≈400nm was measured. And the largest ever radiative heat flux using graphene/hBN/graphene multilayers under similar gap space was obtained.

Mimicking Surface Plasmons with Structured Surfaces
TL;DR: It is established that electromagnetic waves in both materials are governed by an effective permittivity of the same plasma form, which allows the creation of designer surface plasmons with almost arbitrary dispersion in frequency and in space.

Electromagnetic parameter retrieval from inhomogeneous metamaterials
David R. Smith,David R. Smith,D. C. Vier,Th. Koschny,Th. Koschny,Costas M. Soukoulis,Costas M. Soukoulis +6 more
TL;DR: It is shown here that a modification of the standard S-parameter retrieval procedure yields physically reasonable values for the retrieved electromagnetic parameters, even when there is significant inhomogeneity within the unit cell of the structure.

Formulation for stable and efficient implementation of the rigorous coupled-wave analysis of binary gratings
TL;DR: In this paper, the authors presented a stable and efficient numerical implementation of the analysis technique for one-dimensional binary gratings for both TE and TM polarization and for the general case of conical diffraction.

Far-field optical hyperlens magnifying sub-diffraction-limited objects.
TL;DR: Experimental demonstration of the optical hyperlens for sub-diffraction-limited imaging in the far field and opens up possibilities in applications such as real-time biomolecular imaging and nanolithography.

Use of Fourier series in the analysis of discontinuous periodic structures
TL;DR: The recent reformulation of the coupled-wave method by Lalanne and Morris as mentioned in this paper, which dramatically improves the convergence of the method for metallic gratings in TM polarization, is given a firm mathematical foundation in this paper.
