Metamaterials (MMs) with artificial structures have extraordinary physical properties that
cannot be found in traditional materials. MMs with electromagnetic wave absorption (MMAs) …

Silicon-based nonlinear metasurfaces were implemented only with third-order nonlinearity
due to the crystal centrosymmetry and the efficiencies are considerably low, which hinders …

We propose and explore a physical mechanism for the stabilization of the complex
spatiotemporal dynamics in arrays (bars) of broad area laser diodes taking advantage of the …

In this Letter, the design of a directional optical cloaking by a genetic algorithm is proposed
and realized experimentally. A three-dimensional finite-difference time-domain method is …

This study delves into the innovative landscape of metasurfaces, with a particular focus on
their role in achieving EM illusion (EMI) a facet of paramount significance. The control of EM …

The discovery of unidirectional invisibility and its broadband realization in optical media
satisfying spatial Kramers–Kronig relations are important landmarks of non-Hermitian …

In this study, the design of a directional cloaking based on the Luneburg lens system is
proposed and its operating principle is experimentally verified. The cloaking concept is …

Metasurface‐tuning is presented as a solution to camouflage high‐index and electrically
large dielectric parasitic scatterers. By incorporating metasurfaces into the dielectric volume …

We present here the design, fabrication and experimental demonstration of a composite
woodpile structure for integral imaging and invisibility cloaking. The structure composed of …

Illusion devices are usually designed using transformation optics. Here, a new method is
proposed to achieve optical illusions without external devices by elaborately manipulating …
