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…
Observation of helical pulses
Ren Wang, Shuai Shi, Zeyi Zhang +4
Ultrafast spatiotemporal vortex pulses constitute a category within spatiotemporal topological waves. Nevertheless, the experimental realization of helical pulses single or few cyc…
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…
