Vortex rings are mysterious and fascinating natural phenomena that show amazing structure and behavior in both the air and electromagnetic waves.
Imagine an air cannon that can fire vortex rings, creating a perfect air vortex that spreads gracefully through the air, like an invisible hand outlining elegant curves in the sky.
This vortex phenomenon is not only a wonder of physics, but also a masterpiece of nature.
, The creation of air vortices is an interesting combination of science and aesthetics.
When the air cannon is launched, the instantaneous pressure difference will cause the air to form a rotating annular structure that stably spreads in the air, demonstrating the unique shape and dynamics of the vortex.
Applying this principle to electromagnetic waves, scientists envision the development of an “electromagnetic vortex cannon” that can directly launch electromagnetic vortex rings.
With the unremitting efforts of researchers, this idea is gradually becoming a reality.
According to foreign media reports, Wang Ren, associate professor at the University of Electronic Science and Technology of China, Shen Yijie, assistant professor at Nanyang Technological University in Singapore, and researchers at the University of Southampton in the United Kingdom have proposed a method to directly transmit electromagnetic vortices using coaxial horn antennas.
They observed the elastic propagation characteristics and skyrmion topology of these vortices.
