Toroidal Electromagnetic pulses

I was doing research today and cool stuff came up

Toroidal electromagnetic pulses

Toroidal electromagnetic pulses can be generated using a device known as a horn microwave antenna. This electromagnetic “vortex cannon” produces skyrmion topological structures that might be employed for information encoding or for probing the dynamics of light–matter interactions, according to its developers in China, Singapore and the UK.

Examples of toroidal or doughnut-like topology abound in physics – in objects such as Mobius strips and Klein bottles, for example. It is also seen in simpler structures like smoke rings in air and vortex rings in water, as well as in nuclear currents. Until now, however, no one had succeeded in directly generating this topology in electromagnetic waves.

Single-antenna super-resolution positioning with nonseparable toroidal pulses

Topological electromagnetic fields exhibit vast potential applications in information and energy transmission12,13,14,15,16,17,18 and super-resolution metrology or microscopy19,20,21,22,23,24, thereby offering a potential avenue for achieving precise 3D positioning based on a single transmission antenna in free space. In 1996, Hellwarth and Nouchi introduced toroidal pulses, an exact solution to Maxwell’s equations25, which possess complex non-transverse skyrmion topological structures26,27,28,29, space-time nonseparability 30,31,32,33, and strong interactions with matter34,35. Recently, electromagnetic toroidal pulses have been successfully generated in the optics, terahertz, and microwave36,37,38, laying the foundation for their practical applications. However, to the best of our knowledge, there have been no reports of successful experimental implementations of toroidal pulses until now.

skyrmions

Recent developments in nanophotonics and structured light have led to the creation of similar topological particle-like textures in optical fields, known as optical skyrmions. In contrast to topological spin textures embedded in matter, optical skyrmions can propagate in free space, enabling long-distance information transfer. Creating and controlling free-space topological textures with structured light is an emerging field that will drive conceptual revolutions from solid-state data storage to dynamic long-range information transfer

It's just missing a double helix.

I also found DBD again, cool stuff with delta wings apparently


https://www.researchgate.net/figure/DBD-..._256442125

The flow over a delta wing at high angles of attack is characterized by the presence of two large-scale primary vortices on the leeward side of the wing. These vortices contribute substantially to lift production at high angles of attack. Therefore, vortex breakdown, which can be induced by unfavorable pressure gradients or freestream disturbances,...

Yeah the DBD reminds me of this stuff

HE HUNT FOR

The B-2 had already shown its ability to fly halfway around the world and back—a 37-hour, 29,000-nautical-mile return flight from Whiteman Air Force Base, Missouri, to Guam in the Pacific with several air-to-air refuelings en route. With gravity shielding—if such a thing could be moved from the laboratory to a fully fledged aircraft program— either its range could be extended or the number of midair refuelings cut. Either of these would make the technology a powerful draw

fuel saving maybe

LaViolette had written an elegant thesis about the B-2 and its antigravitational properties soon after the publication of a revelatory article
in Aviation Week, the "bible" of the U.S. aerospace industry, in which
a number of black-world engineers had whistle-blown to the author,
the magazine's West Coast editor, Bill Scott, about a host of amazing
new technologies supposedly being developed in the deeply classified
environment. One of these related to "electrostatic field-generating
techniques" in the B-2's wing leading edge with a view to reducing the
giant Stealth Bomber's radar cross section.
