Differentiable eigendecomposition-free RCWA for full-tensor anisotropic photonics
Enbo Yang, Qiang Song, Weiwei Cai
Full-tensor anisotropy transforms rigorous coupled-wave analysis (RCWA) into a large, fully coupled non-Hermitian eigenproblem, making eigendecomposition expensive and difficult to…

Ultracompact Wide-FOV Near-infrared Camera with Wafer-level Manufactured Meta-Aspheric Lens
Chuirong Chi, Qichao Hou, Guangyuan Zhao +10
Overcoming the trade-off between wide field of view (FOV) and compactness remains a central challenge for integrating near-infrared (NIR) imaging into smartphones and AR glasses. E…
