For more than seven decades, hexagonal boron nitride (hBN) has been employed as an
inert, thermally stable engineering ceramic; since 2010, it has also been used as the optimal …

Molecular plasmonics, the area which deals with the interactions between surface plasmons
and molecules, has received enormous interest in fundamental research and found …

Manipulating the properties of the isofrequency contours (IFCs) of materials provides a
powerful means of controlling the interaction between light and matter. Hyperbolic …

This review aims at providing a comprehensive and updated picture of the field of hyperbolic
metamaterials, from the foundations to the most recent progresses and future perspectives …

Uniaxial materials whose axial and tangential permittivities have opposite signs are referred
to as indefinite or hyperbolic media. In such materials, light propagation is unusual leading …

Recent advances in nanofabrication and characterization technologies have spurred many
breakthroughs in the field of optical metamaterials and metasurfaces that provide novel …

This Colloquium presents an overview of the research on nonlinear electromagnetic
metamaterials. The developed theoretical approaches and experimental designs are …

We explore the unusual electromagnetic response of ultrathin anisotropic σ-near-zero
uniaxial metasurfaces, demonstrating extreme topological transitions—from closed elliptical …

Holography has numerous applications because of its capability of arbitrary wavefront
modulation. Computer-generated holograms (CGHs) take it a big step forward. Conventional …

In this Perspective, we discuss the physics and potential applications of planar hyperbolic
metasurfaces (MTSs), with emphasis on their in-plane and near-field responses. After …
