Fano-like resonant coupling of electromagnetic radiation with planar waveguiding modes of
nanostructured thin films is proposed and realized experimentally. Different from …

In this paper, a spatially selective (SS) structure is investigated through the critical jump
characteristic when the permittivity of the epsilon-negative (ENG) materials approaches …

In this paper, three categories of Janus angle absorption structures for terahertz (THz) waves
are realized by operating the edge hopping property of the photonic band gaps (PBGs) and …

The goal and essential parameter of laser light conversion is achieving emitted radiation of
higher brightness. For many applications, the laser beam must have the highest available …

Spatial filtering is an important mechanism to improve the spatial quality of laser beams.
Typically, a confocal arrangement of lenses with a diaphragm in the focal plane is used for …

The Janus metastructure (JMS) is constructed in a special way so that the electromagnetic
waves (EWs) propagate in the artificially constructed metastructure from different directions …

Zero incidence angle spatial filters of a compact design can be very useful, among others,
for intracavity spatial filtering in high-power micro-lasers. Typically, micro-lasers, especially …

We propose a translationally invariant metamirror for light filtering in reflection. The device
consists of a thin transverse grating in the micron scale positioned in front of a flat mirror. We …

In this paper, the investigation of the angular selective windows (ASWs) is realized by
constructing multilayer ceramic photonic crystals 1 (MCPC1) containing superconductor …

We propose and demonstrate experimentally super-collimation of light beams by an
axisymmetric diffractive metamirror—an axisymmetric concentric dielectric ring structure …
