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…
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…
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…
