Ny radioamatør mode?: Vortex-kanon-mode?

Kunne du tænke dig at være den første til at teste vortex-kanon-mode?

Formentlig ultrahøj retningsforstærkning?

Det kunne være en kommunikationsrevolution?

Ny ultraretningsbestemt RADAR?

Ny ultraretningsbestemt energioverførsel?

Hvad tænker du?

September 10, 2024, Chinese Scientists Have Developed an Electromagnetic Vortex Cannon.
Vortex rings, both in air and electromagnetic waves, are fascinating structures. 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.

Citat: "...
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.”

Ved du ikke hvad skyrmion - det gør jeg heller ikke :-) Det er ikke et morgenmadsprodukt - her er en artikler om skyrmion:

Citat: "...
A skyrmion can be described as a swirling quasi-particle, a knot of twisting field lines, or a subatomic hurricane. They're also one of the most difficult physics concepts for humans to understand.

PS: Man kan sagtens anvende teknologiske dimser man ikke forstår - tænk fx på computere, non-smartphones osv...

Svar til #1:
Altid godt at vågne op til en gang copy paste. Prøv med egne ord?

Svar til #2:
Det er vel fint nok, at han finder artiklerne frem til os?

Mvh.

Svar til #2:

Hvorfor skulle han sidde og skrive all den info med (med egne ord) som findes på de sider ? Det ville da være både tåbeligt og spild af tid :-D Hej hej

Svar til #3 og 4:

Helt enig.
