Multi-dimensional wave steering with higher-order topological phononic crystal

Changqing Xu, Zeguo Chen, Guanqing Zhang +2

The recent discovery and realizations of higher-order topological insulators enrich the fundamental studies on topological phases. Here, we report three-dimensional (3D) wave-steer…

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…

Deterministic and probabilistic deep learning models for inverse design of broadband acoustic cloak

Waqas W. Ahmed, Mohamed Farhat, Xiangliang Zhang +1

Concealing an object from incoming waves (light and/or sound) remained science fiction for a long time due to the absence of wave-shielding materials in nature. Yet, the invention…

Scattering Cancellation Technique for Acoustic Spinning Objects

Mohamed Farhat, Sebastien Guenneau, Andrea Alu +1

The scattering cancellation technique (SCT) has proved to be an effective way to render static objects invisible to electromagnetic and acoustic waves. However, rotating cylindrica…

Restricted Hilbert transform for non-Hermitian management of fields

W. W. Ahmed, R. Herrero, M. Botey +2

Non-Hermitian systems exploiting the synergy between gain and loss have recently become the focus of interest to discover novel physical phenomena. The spatial symmetry breaking in…

Three-dimensional acoustic double-zero-index medium with a Dirac-like point

Changqing Xu, Guancong Ma, Ze-Guo Chen +4

We report a design and experimental realization of a three-dimensional (3D) acoustic double-zero-index medium (DZIM), whose effective mass density and compressibility are nearly ze…
