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…
Space-Time Fresnel Prism
Zhiyu Li, Xikui Ma, Amir Bahrami +2
Space-time modulation-based metamaterials have recently spurred considerable interest, owing to the fundamental addition of the time dimension to the medium parameters, and resulti…
Observation of higher-order exceptional points in pseudo-Hermitian radio-frequency circuits
Ke Yin, Xianglin Hao, Yuangen Huang +3
Exceptional points (EP) in non-Hermitian systems have been widely investigated due to their enhanced sensitivity in comparison to standard systems. In this letter, we report the ob…
Tunable Perfect Anomalous Reflection Using Passive Aperiodic Gratings
Yongming Li, Xikui Ma, Xuchen Wang +3
Realizing continuous sweeping of perfect anomalous reflection in a wide angular range has become a technical challenge. This challenge cannot be overcome by the conventional aperio…
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…
