Free-electron Brewster radiation
Ruoxi Chen, Jialin Chen, Zheng Gong +7
Free-electron radiation offers an enticing route to create light emission at arbitrary spectral regime. However, this type of light emission is generally weak, which is intrinsical…
Recent advances of transition radiation: fundamentals and applications
Ruoxi Chen, Zheng Gong, Jialin Chen +4
Transition radiation is a fundamental process of light emission and occurs whenever a charged particle moves across an inhomogeneous region. One feature of transition radiation is…
Low-velocity-favored transition radiation
Jialin Chen, Ruoxi Chen, Zheng Gong +8
When a charged particle penetrates through an optical interface, photon emissions emerge - a phenomenon known as transition radiation. Being paramount to fundamental physics, trans…
A perspective on meta-boundaries
Xinyan Zhang, Jialin Chen, Ruoxi Chen +4
The judicious design of electromagnetic boundary provides a crucial route to control light-matter interactions, and it is thus fundamental to basic science and practical applicatio…
