Parity Metamaterials and Dynamic Acoustic Mimicry
Jinjie Shi, Hongchen Chu, Aurelien Merkel +4
While parity transformation represents a fundamental symmetry operation in physics, its implications remain underexplored in metamaterial science. Here, we introduce a framework le…
Metamaterial sound absorbers based on microperforated panels: an approach toward enhanced flexibility and near-limit broadband performance
Jinjie Shi, Jie Luo, Chenkai Liu +6
Traditional microperforated panels (MPPs) and metamaterial-based sound absorbers rely on local resonances or multi-resonator designs, which limit their bandwidth, angular applicabi…
Transparent matte surfaces enabled by asymmetric diffusion of white light
Hongchen Chu, Xiang Xiong, Nicholas X. Fang +5
The traditional wisdom for achieving transparency is to minimize disordered scattering within and on the surface of materials, so as to avoid translucency. However, the lack of dis…
Relaying Topological Interface States for Negative Refraction of Bulk Waves
Hongchen Chu, Ze-Guo Chen, Yun Lai +1
Topological notions in physics have become a powerful perspective that leads to the discoveries of topological interface states (TISs). In this work, we present a scheme to achieve…
Three-dimensional Electromagnetic Void Space
Changqing Xu, Hongchen Chu, Jie Luo +3
We report a realization of three-dimensional (3D) electromagnetic void space. Despite occupying a finite volume of space, such a medium is optically equivalent to an infinitesimal…
Breakdown of Maxwell Garnett theory due to evanescent fields at deep-subwavelength scale
Ting Dong, Jie Luo, Hongchen Chu +2
Deep-subwavelength all-dielectric composite materials are believed to tightly obey the Maxwell Garnett effective medium theory. Here, we demonstrate that the Maxwell Garnett theory…
Pseudo-Hermitian Systems Constructed by Transformation Optics with Robustly Balanced Loss and Gain
Liyou Luo, Jie Luo, Hongchen Chu +1
Non-Hermitian systems with parity-time symmetry have been found to exhibit real spectra of eigenvalues, indicating a balance between the loss and gain. However, such a balance is n…
Ultra-broadband reflectionless Brewster absorber protected by reciprocity
Jie Luo, Hongchen Chu, Ruwen Peng +3
The Brewster's law predicts zero reflection of p-polarization on a dielectric surface at a particular angle. However, when loss is introduced into the permittivity of the dielectri…
