Beyond the PT-Broken Phase: Constant-Frequency Oscillation from Floquet Hybridization
Xiaoke Gao, Xiaoyin Sha, Xunyan Sun +3
Constant-frequency oscillation is usually tied to the broken phase of a spatially coupled PT-symmetric dimer, where the eigenfrequencies form a complex-conjugate pair with a fixed…
Focal control and light tracing on curved surfaces with isotropic transformation medium
Xiaoyu Zhao, Longfei Shi, Zhuoyu Zhang +4
Optics related to non-Euclidean geometry has been attracting growing interest for emerged novel phenomena and the analog for general relativity, while most studies are limited to t…
Topological invariant of non-Hermitian space-time modulated photonic crystals
Xiaoke Gao, Xiaoyu Zhao, Jiawei Wang +2
We propose a medium transformation approach to formulate the adjoint system of space-time modulated photonic crystals (STMPCs), essential for the bi-orthogonal Berry connection whe…
Free electron emission in vacuum assisted by photonic time crystals
Xiaoke Gao, Xiaoyu Zhao, Xikui Ma +1
The Cerenkov radiation and the Smith-Purcell effect state that free electron emission occurs exclusively in dielectrics when the velocity of the particles exceeds the speed of ligh…
Controlling Electromagnetic Surface Waves with Conformal Transformation Optics
Xiaoyu Zhao, Hong Deng, Xiaoke Gao +2
The application of transformation optics to the development of intriguing electromagnetic devices can produce weakly anisotropic or isotropic media with the assistance of quasi-con…
Analysis and design of transition radiation in layered uniaxial crystals using Tandem neural networks
Xiaoke Gao, Xiaoyu Zhao, Ruoyu Huang +3
With the flourishing development of nanophotonics, Cherenkov radiation pattern can be designed to achieve superior performance in particle detection by fine-tuning the properties o…
Plasmon Localization Assisted by Conformal Symmetry
Lizhen Lu, Emanuele Galiffi, Kun Ding +3
Plasmonic systems have attracted remarkable interest due to their application to the subwavelength confinement of light and the associated enhancement of light-matter interactions.…
