A centimeter-scale achromatic hybrid metalens with polarization-insensitivity in the visible
Tie Hu, Shengqi Wang, Yunxuan Wei +4
Metalenses, featuring ultra-compactness and CMOS compatibility, are limited by the compromise between the diameter, numerical aperture, and working waveband. To address this proble…
Topological Dirac Nodal-net Fermions in AlB-type TiB and ZrB
Xing Feng, Changming Yue, Zhida Song +2
Based on first-principles calculations and effective model analysis, a Dirac nodal-net semimetal state is recognized in AlB-type TiB and ZrB when spin-orbit coupling (S…
Laminar Tight Cuts in Matching Covered Graphs
Guantao Chen, Xing Feng, Fuliang Lu +2
An edge cut of a graph is {\it tight} if for every perfect matching of .~Barrier cuts and 2-separation cuts are called {\it ELP-cuts}, which are two i…
Generalized Hartmann-Shack array of dielectric metalens sub-arrays for polarimetric beam profiling
Zhenyu Yang, Zhaokun Wang, Yuxi Wang +8
To define and characterize optical systems, obtaining information on the amplitude, phase, and polarization profile of optical beams is of utmost importance. Polarimetry using bulk…
Design of an achromatic zoom metalens doublet in the visible
Tie Hu, Xing Feng, Yuanxuan Wei +4
Zoom metalens doublet exhibits unprecedented advantages over the traditional zoom lens in many aspects, like ultra-compactness, CMOS compatibility, and miniaturization. However, mo…
Phase-Only Holographic Assisted Planar Printing for Massively Multiplexed Optical Display and Encryption
Yunxuan Wei, Tie Hu, Xing Feng +2
Multiplexed planar printings, made of single or few layer micro and nano optical platforms, are essential for high capacity display, information storage and encryption. Although ha…
A concentration phenomenon for -extra edge-connectivity reliability analysis of enhanced hypercubes with exponentially many faulty links
Yali Sun, Mingzu Zhang, Xing Feng +1
Reliability assessment of interconnection networks is critical to the design and maintenance of multiprocessor systems. The -enhanced hypercube , as a variation of…
Compact optical polarization-insensitive zoom metalens-doublet
Yunxuan Wei, Yuxi Wang, Xing Feng +8
Metasurface-based lenses (metalenses) offer specific conceptual advantages compared to ordinary refractive lenses. For example, it is possible to tune the focal length of a metalen…
Methods and strategies for improving the novel view synthesis quality of neural radiation field
Shun Fang, Ming Cui, Xing Feng +1
Neural Radiation Field (NeRF) technology can learn a 3D implicit model of a scene from 2D images and synthesize realistic novel view images. This technology has received widespread…
Exploration and Improvement of Nerf-based 3D Scene Editing Techniques
Shun Fang, Ming Cui, Xing Feng +1
NeRF's high-quality scene synthesis capability was quickly accepted by scholars in the years after it was proposed, and significant progress has been made in 3D scene representatio…
Temperature-dependent hardness of diamond-structured covalent materials
Xing Feng, Jianwei Xiao, Bin Wen +4
Understanding temperature-dependent hardness of covalent materials is not only of fundamental scientific interest, but also of crucial importance for technical applications. In thi…
Equivalence classes in matching covered graphs
Fuliang Lu, Nishad Kothari, Xing Feng +1
A connected graph , of order two or more, is matching covered if each edge lies in some \pema. The tight cut decomposition of a matching covered graph yields a list of brick…
A real-time rendering method for high albedo anisotropic materials with multiple scattering
Shun Fang, Xing Feng, Ming Cui
We propose a neural network-based real-time volume rendering method for realistic and efficient rendering of volumetric media. The traditional volume rendering method uses path tra…
-invariant edges in essentially 4-edge-connected near-bipartite cubic bricks
Fuliang Lu, Xing Feng, Yan Wang
A {\em brick} is a non-bipartite matching covered graph without non-trivial tight cuts. Bricks are building blocks of matching covered graphs. We say that an edge in a brick $G…
Efficient Graph Edit Distance Computation and Verification via Anchor-aware Lower Bound Estimation
Lijun Chang, Xing Feng, Xuemin Lin +2
