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…
Experimental realization of a full-band wave antireflection based on temporal taper metamaterials
Haonan Hou, Kai Peng, Yangkai Wang +5
As time can be introduced as an additional degree of freedom, temporal metamaterials nowadays open up new avenues for wave control and manipulation. Among these advancements, tempo…
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…
Spatiotemporal Superfocusing
Qianru Yang, Haotian Wu, Hao Hu +3
Superfocusing confines light within subwavelength structures, breaking the diffraction limit. Structures with spatial singularities, such as metallic cones, are crucial to enable n…
Momentum flatband and superluminal propagation in a photonic time Moiré superlattice
Linyang Zou, Hao Hu, Haotian Wu +4
Flat bands typically describe energy bands whose energy dispersion is entirely or almost entirely degenerate. One effective method to form flat bands is by constructing Moiré supe…
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…
