Electromagnetic (EM) tunability of microwire metacomposites relies on topology, external
stimuli, and/or hybridization, which are burdensome and restricted to narrow frequency …

The invisibility cloak, a long-standing fantastic dream for humans, has become more
tangible with the development of metamaterials. Recently, metasurface-based invisibility …

Accidental degeneracy plays an important role in the generation of novel band dispersions.
Photonic structures that exhibit an accidental Dirac-like conical dispersion at the center of …

Materials with a spatially uniform but temporally varying optical response have applications
ranging from magnetic field-free optical isolators to fundamental studies of quantum field …

Coherent perfect absorption (CPA), as time-reversed lasing, arises from appropriate wave
interference within absorbers, offering flexible control over wave absorption. Typically, this …

Impurities usually play an important role in modifying the bulk properties of electronic or
electromagnetic materials. In this work, we demonstrate a way to break this discipline and …

We report the first realization of a three-dimensional (3D) acoustic double-zero-index
medium (DZIM) made of a cubic lattice of metal rods. While the past decade has seen …

Coherent perfect absorption, as time‐reversed lasing, is achieved via appropriate
interference of waves in absorbers and provides attractive opportunities for flexible control of …

Electromagnetic void space is a medium, while geometrically occupying a finite volume of
space, optically equivalent to an infinitesimal point, in which electromagnetic waves do not …

We report a general method to design a unique type of a non-Hermitian electromagnetic
double-near-zero index medium by a two-dimensional photonic crystal. The synergy of a …
