Twin reflections from a moving space-time boundary
Yukun Yang, Hao Hu, Youxiu Yu +7
An interluminal interface, a space-time boundary propagating at a velocity between the group velocities of the surrounding media, enables extraordinary wave phenomena such as nonre…
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…
Observation of wave amplification and temporal topological state in a genuine photonic time crystal
Jiang Xiong, Xudong Zhang, Longji Duan +6
Photonic time crystals (PTCs) are materials whose dielectric permittivity is periodically modulated in time, giving rise to bandgaps not in energy-as in conventional photonic cryst…
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…
