A hyperbolic material (HM) is an optical material that exhibits a unique property of having
anisotropy with simultaneously different signs of the permittivity tensor components. Such a …

This is a short communication based on recent high-impact publications related to how
various chemical materials and substrate modifications could be tuned for nano-and …

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

Optical metamaterials have redefined how we understand light in notable ways: from strong
response to optical magnetic fields, negative refraction, fast and slow light propagation in …

Conventional defect modes in all-dielectric 1D photonic crystals (PCs) are polarization-
insensitive. This poses a great challenge in achieving high-performance polarization …

We introduce a new “universality class” of artificial optical media—photonic hypercrystals.
These hyperbolic metamaterials, with periodic spatial variation of dielectric permittivity on …

Organic, inorganic or hybrid devices in the liquid state, kept in a fixed volume by surface
tension or by a confining membrane that protects them from a harsh environment, could be …

We theoretically study the electromagnetic response of type-I and type-II centrosymmetric
Weyl metals. We derive an anisotropic permittivity tensor with off-diagonal elements to …

Photonic crystals (PCs) have emerged as one of the most widely used platforms for
controlling light–matter interaction in solid-state systems. They rely on Bragg scattering from …

Recently developed parity (P) and time-reversal (T) symmetric non-Hermitian systems
govern a rich variety of new and characteristically distinct physical properties, which may or …
