Toroidal helical pulses
Shuai Shi, Hongcheng Zhou, Junjie Shao +7
Toroidal topologies and helicity are pervasive in nature and hold basic importance in scientific research. In particular, the interplay between these features gives rise to fascina…
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…
Double-Helix Singularity and Vortex-Antivortex Annihilation in Space-Time Helical Pulses
Shuai Shi, Ren Wang, Minhui Xiong +3
Topological structures reveal the hidden secrets and beauty in nature, such as the double helix in DNA, whilst, the manipula-tion of which in physical fields, especially in ultrafa…
Hybrid electromagnetic toroidal vortices
Ren Wang, Beier Ying, Shuai Shi +4
The ubiquitous occurrence of toroidal vortices or vortex rings in fluid-dynamic scenarios in nature has garnered significant attention of scientific frontier, whilst, the electroma…
Propagation-invariant strongly longitudinally polarized toroidal pulses
Ren Wang, Ding-Tao Yang, Tao Xin +3
Recent advancements in optical, terahertz, and microwave systems have unveiled non-transverse optical toroidal pulses characterized by skyrmionic topologies, fractal-like singulari…
Time-varying k-domain modulation around a point sink in time reversal cavity
Xin Liu, Jin-Shan Cui, Ren Wang +2
This paper derives and investigates a time-varying k-domain modulation in vector form using a time-reversal (TR) field decomposition theory proposed for the first time. First, the…
Space Time Nonseparable Electromagnetic Vortices
Minhui Xiong, Ren Wang, Qinyu Zhou +1
In structured light with controllable degrees of freedom (DoFs), the vortex beams carrying orbital angular momentum (OAM) give access to provide additional degrees of freedom for i…
