Experiment-based deep learning approach for power allocation with a programmable metasurface
Jingxin Zhang, Jiawei Xi, Peixing Li +3
Deep learning, as a highly efficient method for metasurface inverse design, commonly use simulation data to train deep neural networks (DNNs) that can map desired functionalities t…
Electromagnetic Near-Field Mutual Coupling Suppression with Active Janus Sources
Bo Xue, Kayode Adedotun Oyesina, Alex M. H. Wong
Electric dipoles and magnetic dipoles are the most fundamental particles in electromagnetic theory. Huygens and Janus sources, formed by the orthogonal combination of electric and…
Bipartite Dielectric Huygens' Metasurface for Anomalous Refraction
Abhishek Sharma, Alex M. H. Wong
Huygens' metasurfaces - fundamentally based on Schelkunoff's equivalence principle, Huygens' metasurfaces consist of a two-dimensional array of Huygens' sources formed by co-locate…
Generation of superhelical time-varying OAM beam with space-time-coding digital metasurface
Jingxin Zhang, Peixing Li, Alex M H Wong +1
The recently proposed extreme-ultraviolet (EUV) beams with time-varying orbital angular momentum (OAM) realized by high-harmonic generation (HHG) provides extraordinary tools for q…
Discrete Huygens' Metasurface: Realizing Anomalous Reflection and Diffraction Mode Circulation with a Robust, Broadband and Simple Design
Chu Qi, Alex M. H. Wong
Metasurfaces composed of subwavelength unit cells usually require a large number of unit cells which leads to complicated design and optimization. Aggressive discretization in a me…
Active Huygens' Box: Metasurface-Enabled Arbitrary Electromagnetic Wave Generation Inside a Cavity
Alex M. H. Wong, George V. Eleftheriades
This work investigates the generation of arbitrary electromagnetic waveforms inside a geometrical area enclosed by an active metasurface. We introduce the contraption of the Huygen…
