Inverse Design of Mirror‐Symmetric Disordered Systems for Broadband Perfect Transmission

Laser &Photonics Reviews, EarlyView.
This work introduces an inverse design approach to achieve broadband perfect wave transmission in mirror‐symmetric disordered media. Leveraging symmetry simplifies optimization and enables control of multiple reflectionless states. Experiments in microwave waveguides confirm the design of exceptional points, bandpass filters, and broadband quasi ...

Long‐Range Exciton Energy Transfer in Two‐Dimensional Materials

Laser &Photonics Reviews, EarlyView.
This review highlights recent advances in long‐range exciton energy transfer within planar 2D‐material architectures. It emphasizes the emergence of self‐hybridized excitonpolaritons, exciton coupling to surface plasmon polaritons and plasmonic lattices, and the role of dipoledipole transfer pathways in enabling efficient nanoscale energy transport ...

Reconfigurable Circularly Polarized Terahertz Emission from vdW Ferroelectric NbOI2

Laser &Photonics Reviews, EarlyView.
A controllable chiral terahertz pulse can be generated using a simple dual‐flake vdW ferroelectric NbOI2 emitter in which the polar axes of the two NbOI2 flakes are orthogonal. Both the chirality and the ellipticity can be manipulated by varying the separation distance and the orientations of their polar axes.

Metamaterial Mechanisms

Proceedings of the 29th Annual Symposium on User Interface Software and Technology, 2016
Recently, researchers started to engineer not only the outer shape of objects, but also their internal microstructure. Such objects, typically based on 3D cell grids, are also known as metamaterials. Metamaterials have been used, for example, to create materials with soft and hard regions.So far, metamaterials were understood as materials-we want to ...

Disordered mechanical metamaterials

Nature Reviews Physics, 2023
Mechanical metamaterials are a class of artificial materials whose geometry is engineered to have peculiar mechanical properties or programmed responses that are difficult to find in conventional materials. Typically, metamaterials are periodic, but incorporating disorder into their design can provide improved functionalities over ordered structures ...
