Learning light scattering from operator parameter spaces to Galerkin-consistent solution spaces
Lida Liu, Jingwei Wang, Wei Cao +2
Efficient and generalizable full-wave simulation is essential for nanophotonic analysis and inverse design, yet existing methods face a tradeoff between the high computational cost…
Nonsymmorphic symmetry adapted finite element modeling of glide-symmetric photonic structures
Lida Liu, Jingwei Wang, Yuhao Jing +3
Space group theory is pivotal in the design of nanophotonics devices, enabling the characterization of periodic optical structures such as photonic crystals. The aim of this study…
Categorize coalescing quasi-normal modes through far-field scattering patterns
Jingwei Wang, Yuntian Chen, Wei Liu
Resonances in the form of quasi-normal modes (QNMs) for open scattering systems can be generally identified in the far field through peaks of scattering spectra (\textit{e.g.} cros…
Quasi-normal modes empowered coherent control of electromagnetic interactions
Jingwei Wang, Pengxiang Wang, Chaofan Zhang +2
Quasi-normal modes (QNMs) and coherent control of light-matter interactions (through synchronized multiple coherent incident waves) are profound and pervasive concepts in and beyon…
Numerical approximation of slowlingly varying envelope in finite element electromagnetism: a ray-wave method of modeling multi-scale devices
Fan Xiao, Jingwei Wang, Zhongfei Xiong +1
In this work we propose an efficient and accurate multi-scale optical simulation algorithm by applying a numerical version of slowly varying envelope approximation in FEM. Specific…
