Twin reflections from a moving space-time boundary
Yukun Yang, Hao Hu, Youxiu Yu +7
The authors experimentally demonstrate that a moving space‑time boundary (an interluminal interface) splits an incoming wave into one transmitted and two reflected waves, confirmin…
Fundamentals and Applications of Time-varying Media: A Review
Youxiu Yu, Hao Hu, Qianru Yang +4
Time-varying media, characterized by dynamic or spacetime-modulated constitutive parameters such as permittivity and permeability, have recently emerged as a transformative paradig…
Topologically protected edge states in time photonic crystals with chiral symmetry
Yukun Yang, Hao Hu, Liangliang Liu +7
Time photonic crystals are media in which their electromagnetic parameters are modulated periodically in time, showing promising applications in non-resonant lasers and particle ac…
A time grating approach to ultrahigh-Q guided mode resonance
Youxiu Yu, Xiaofeng Xu, Yang Long +4
Guided mode resonance (GMR), the resonant coupling of free-space light into leaky waveguide modes, is traditionally achieved with periodic patterned structures. However, this appro…
Generalized coherent wave control at dynamic interfaces
Youxiu Yu, Dongliang Gao, Yukun Yang +10
Coherent wave control is of key importance across a broad range of fields such as electromagnetics, photonics, and acoustics. It enables us to amplify or suppress the outgoing wave…
