LightSlingers

LightSlingers--- yes, this is an antenna design.

Looking for your next experimental antenna project (what ham isn't ?)
Take a look--- these will transform the way you think about antennas.

Interesting. It sounds like they may be modulating light at RF frequencies then using optical means to focus the light resulting in much narrower beamwidths at light frequency vs RF frequency, but the end user is receiving the tightly focused RF frequencies. Maybe similar to the super focused audio blasters used by the military to control crowds? Those have a large piezo transducer buzzing at 40KHz or so then they modulate that with audible frequencies and get the super tight acoustic radiation pattern of a large piezo transducer at 40KHz but human range audio is heard at a distance in a very tightly controlled pattern.

BTW I have an aunt and uncle that worked at the lab in the 60s and 70s. Auntie died, we think from exposure to plutonium at some point in her career as a nurse.

Intriguing Lauri, I'm interested in different sizes and price ranges. I'm going to research this some more.

Way cool!
The video and text raised a variety of questions in my mind. The easiest for me to articulate at the moment is the correlation between operational RF frequency and physical size of the LightSlinger, along with power handling capabilities.

The description text says, "Unlike conventional antennas, they use polarization currents, animated to faster-than-light speeds, as their emission mechanism. ..." @Lauri-CoyoteFrostbite -please elaborate!

"................. please elaborate!..........."

Oh My ! where to start ?
This is Einsteinian physics------- faster than the speed of light--- Buzz Lightyear "To infinity and Beyond!" stuff.

I did a little digging for something better than myself for a concise semi-explanation without the math--- here's a good starting place

"Light Slinging" can be scaled to frequency requirements, and once understood, it is not beyond an experimenter's ability to reproduce. When I was involved we utilized ion-izing ("X"-ray) radiation as the 'sling'... but light wavelengths are far safer.

I can definitely see this technique finding its niche in amateur radio---- Stay tuned !

This is going to take a couple of read throughs and some fermented grape juice for lubrication!

Next question-can I get a LightSlinger with an SMA connector to fit my Baofeng?

Anyone else thinking of the Clacks towers, from Discworld?

I worked on a project that was sort of the opposite of a LightSlinger and it used some things mentioned in this thread to redirect or absorb RF. I don't think I'm stepping out of bounds here mentioning it since it was described in a patent many years ago. Anyway the patent title had the words "cloaking device for reentry vehicle" (I'm not making this up) and my job was to test it.

I was provided an item to test in a radar cross section range which was outfitted with some stuff so we could create an "environment" around the item. It was quite a thing to see and get working. We then tested for radar reflections across many frequency ranges. I can't tell you the outcome of any testing but I can say at one point the project was quickly taken away from us and the reason was never explained. I won't elaborate on what I think about the reason but you can probably imagine.

Only two possible reasons 1) Alien Technology, 2) You proved it didn't work.

Read the article. There is not enough meat with those potatoes. Beamforming has been with us for ages, small phase differences make drastic effects in far field. How is any of that superluminal? Is it some quantum effect? If an experimenter can do this, I would love to see a drawing. But then how to measure the superluminal? Einstein is rolling in his grave. By the way a quick google search and I found a similar report a decade ago about previous 1981 claim...

The Faster-Than-Light Telegraph That Wasn't

In 1981 physicist Nick Herbert leveraged strange features of quantum mechanics to design a superluminal communication system. The quest to uncover its subtle flaw led to a profound new understanding of the quantum world

Hmm; some of their articles claim Cherernkov radiation. The anti 5G'ers will have a filed day.

Cherenkov radiation - Wikipedia

Theoretical and Experimental Studies of the Emission of Electromagnetic Radiation by Superluminal Polarization Currents

Maxwell’s equations establish that patterns of electric charges and currents can be animated to travel faster than the speed of light in vacuo, c, and that these superluminal distribution patterns emit tightly focused packets of electromagnetic radiation that are fundamentally different from the...

Or maybe the results were above my security clearance. I dunno, who really knows?

Do you have Area 51 clearance? If not = Aliens...

I salute their service. The people that worked in National Laboratories from the 1940s on were selfless in their efforts. Many paid a very high price for what the US demanded.

They served in obscurity and have died without recognition.

Yea its a shame. Uncle did make it to Chief of New Mexico state police after moving on from the lab. Another uncle of mine sold some property in Colorado to a guy that worked there in the 40s and he would ring my uncle up to visit and ride horses when he wasn't working at the lab. His name was Oppenheimer and my uncle had no clue what he did for a living.

There is a really cool museum at Los Alamos-- the Bradbury Science Museum --- a free venue for the hard core geeks and history buffs of Atomic Age. If you visit the "Hill" be sure to look for the statue of "Oppie," and check out the Los Alamos Ranch School--the old boy's private school, founded on the principles of the Boy Scouts.

Not to be missed--- the Chinese restaurants !,..............and the security around the "Tech Areas."

"Bradbury Science Museum" -- Been there!

"the Chinese restaurants" Are there microphones in the booths? and free WIFI?

I applied for a radio tech job there back around the 90's. They have you write your opinion/position on nuclear bombs on the reverse of the application form. I guess I was too honest...

 

[GlobalNorth]

I was looking to buy a residence in Los Alamos, but real estate there is not for the faint of financial heart and means.

I've been to the Bradbury Science Museum as well.

I think it is simply beamforming with phasing of multiple dipoles mounted inside a dielectric that is also serving as a dielectric lens to bend the wave front to accomplish other than linear polarization. I think it is a lot of prior art being marketed with the help of a Linguistics expert.

Sorry about your Aunt. No doubt she was treating accident victims.
