Optical metamaterials are artificially engineered architectures that exhibit desired optical
properties not found in nature. Bespoke design requires the ability to define shape, size …

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

Strongly anisotropic media where the principal components of electric permittivity or
magnetic permeability tensors have opposite signs are termed as hyperbolic media. Such …

A class of strongly anisotropic materials having their principal elements of dielectric
permittivity or magnetic permeability tensors of opposite signs, so-called indefinite or …

Extraordinary optical transmission (EOT) is a term that refers to electromagnetic resonances
through sets of subwavelength apertures in either a flat or a corrugated metal film, providing …

As a basic building block, optical resonant cavities (ORCs) are widely used in light
manipulation. They can confine electromagnetic waves and improve the interaction between …

Metamaterials are the major type of artificially engineered materials which exhibit naturally
unobtainable properties according to how their microarchitectures are engineered. Owing to …

Optical vortices have myriad applications in photonics. Very recently, promising concepts of
spatiotemporal optical vortex (STOV) pulses based on the phase helicity in the space–time …

Anisotropic optical crystals can exhibit a hyperbolic response within the Reststrahlen band
(RB) and support directional polaritonic propagations when interacting with light. Most of the …
