Vanishing Clutter: Fast and Accurate Shape Imaging via Active Cloaking
Haoqiang Xiao, Guang-Hui Zheng
Imaging a target sample in near-field scanning optical microscopy (NSOM) is fundamentally limited by measurement artifacts and data contamination from multiple probe-sample scatter…
Quantitative symmetry-breaking and nonlinear harmonic generation in plasmonics
Hongyu Liu, Zhi-Qiang Miao, Jingfeng Yao +2
We develop a quantitative mathematical theory that offers new perspectives on nonlinear harmonic generation in plasmonic structures arising from symmetry breaking. Focusing on seco…
On surface polariton resonance and its curvature concentration effects from 3D elastic nanorods
Youjun Deng, Hongyu Liu, Wanjing Tang +1
This paper investigates surface polariton resonance (SPR) in three-dimensional elastic metamaterials with nanorod geometry. The primary motivation is to surpass the physical limita…
Microscale Hydrodynamic Cloaking via Geometry Design in a Depth-Varying Hele-Shaw Cell
Hongyu Liu, Zhi-Qiang Miao, Guang-Hui Zheng
We theoretically and numerically demonstrate that hydrodynamic cloaking can be achieved by simply adjusting the geometric depth of a region surrounding an object in microscale flow…
Hybridization theory for plasmon resonance in metallic nanostructures
Qi Lei, Hongyu Liu, Zhi-Qiang Miao +1
In this paper, we investigate the hybridization theory of plasmon resonance in metallic nanostructures, which has been validated by the authors in [31] through a series of experime…
