Recent research has developed methods to emit electromagnetic vortex rings, offering potential applications in communication, sensing, and data processing. This technology may revolutionize wireless networks and pave the way for innovations in data storage and metrology.<br /> https://scitechdaily.com/chinese-scientists-have-developed-an-electromagnetic-vortex-cannon/<br /> Citat: "...<br /> These scientists summarize the operational principle of their electromagnetic cannon: “The principle involves utilizing ultra-wideband, radially polarized, conical coaxial horn antennas to create a rotating electromagnetic wave structure. When the antenna emits, it generates an instantaneous pressure difference that forms these vortex rings, which maintain their shape and energy over long distances. The uniqueness of this method lies in its ability to produce electromagnetic pulses with complex topological features, such as skyrmions, that showcase remarkable resilience and self-healing properties during propagation.”<br /> ..."<br /> <br /> Artikel:<br /> <br /> Reference: “Observation of resilient propagation and free-space skyrmions in toroidal electromagnetic pulses” by Ren Wang, Pan-Yi Bao, Zhi-Qiang Hu, Shuai Shi, Bing-Zhong Wang, Nikolay I.
