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 super…

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…
