but what if you put another split ring inside it, it'll be different
this is just small-ish magloop
i've seen some people make magloops out of bike rims, it's similar sized. the smaller it is the lower radiation resistance, higher currents and voltage on capacitor, narrower bandwidth, and lower efficiency. i don't remember how it scales but efficiency goes up fast with size, 1m dia magloop is already better. downside is that tuning becomes impossible on higher bands (capacitance required for this is below minimum capacitance of capacitor that you have)
also cryonics and "enhanced games" as non-FDA testing ground. i've never seen anyone in more potent denial of their own mortality than Peter Thiel. behind the bastards four-parter on him dissects this
will it antenna? i think it will
split ring resonator has already two different lengths of paths so - even without accounting on how these two interact - you could expect two different frequencies where it's resonant, with peaks perhaps overlapping to a useful degree making a decently wide band possible. it looks a bit like halo antenna with parasitic, downside being that it's probably a bit hard to feed it, circumference has to be halfwave on lowest frequency and if made for HF it'd be gigantic
i think it's more useful to think of magloop as extremely shortened, low impedance, low bandwith halo antenna
ymmw but for me ludic comes off a bit as a sort of a benevolent grifter. difference being that unlike lw poster, ludic probably knows what he's talking about, also i'm not in that field. some of unseriousness and money sloshing around comes from the fact that both dev space and biotechs are quite startuppy, unlike many other fields
i'll have you know that social contract that formed in russia after 90s looks just like that: citizens fuck off from politics in return for some prosperity. every time when russian state expected that that won't last due to things like 2008 crisis or covid or what have you, they started a war as a distraction and to rally around the flag some nationalists. now they're on 4th attempt, this one was due to post-covid recession. difference is, this time they were high on their own supply of propaganda and planned accordingly. they also can't back down because they see it as a weakness, and that would mean a coup
I know that Abe was PM since always, but he's dead for almost three years now
Another good example would be actions Brits took in order to protect the fact that Enigma was broken. For example, when Enigma deciphering indicated that there's warship in a specific area, they would send spotter plane first before attacking it, in order to provide enemy alternative explanation as of how they were discovered. Some operations were aborted entirely for this reason
remember, the entire time until bombs dropped Goldblum wasn't sure that if it was an elaborate bit
at least it's not telegram
edit: orange bar was entirely too long and also i don't know how gradients work
don't ask whose plan tho
Despite what morons on twitter tell you, just because anti-tank weapons exist it doesn't mean that tanks are obsolete. Tanks are useful because tanks do things only tanks can: provide large calibre close fire support while being squarely protected inside a big metal box.
If you are an infantry soldier on tankless side, this sucks. When tanks were first introduced, they were pretty effective because there were no antitank weapons yet. Balance shifted a bit when someone put shaped charge on a rocket/in tiny air-dropped bomb, this forced a change in tactics, armor, and so on. Then, somebody else discovered that C4-metal or rubber-metal lasagna can protect from single shaped charge, this led to development of tandem shaped charges. In terms of current war in Ukraine, we are here (APSs like Trophy exist but these are pretty rare)
You don't have to destroy tank on the frontline to make it useless - it's even better if it's destroyed far behind frontline, but it's not the only option. Tank without fuel can't drive, tank without ammo can't shoot, tank without spares can't be repaired - that's why targeting logistics is important and was pretty successful early in the war
But, after you go through this (russians partially didn't), there are plenty of ways to destroy a tank when it's on the frontline. Assumptions about why and how would that frontline look like made some planners believe that cope cages would be useful, specifically that delusional assumption of three day special operation made them believe that tanks would be used in urban combat.
Cope cage is slat armor fixed to the top of turret. Slat armor works by deforming front part of RPG-7 projectile or similar, which prevents detonation
like this
Cope cage was intended to protect against RPG-7 attack from top, where armour is thinnest. This makes sense, considering how common RPG-7 is in post-soviet stockpiles. This is also why slat armour or ERA is added to any Western equipment - it's much easier to replace busted ERA or steel bars than to send entire tank back for repair.
PG-7V arriving from top could only possibly happen in urban combat, and this is not what happened. Later, when Javelins were proven to be quite effective, cope cages were repackaged by russian propaganda machine as a wunderwaffe armour against them, but this doesn't change that this doesn't work in reality.
But let's say you have a task of destroying a tank with cope cage, what difference would it make?
ATGMs - Side attack
Modern ATGMs will push through up to 1m of RHA, this means these will punch through entire tank and then some, with possible exception of front glacis in modern western tanks. This is the good stuff and it's never available in numbers high enough, so there have to be other options used more liberally. One example of this system is Stugna-P
ATGMs - Top attack
Tanks have much thinner armor on top, this is exploited by some missiles that attack on that side, allowing them to be much lighter and more portable. This is also good stuff, and will completely ignore cope cages, because it's not detonated on impact. Examples include TOW and Javelin. Both types of ATGMs were widely credited with stopping tanks during initial push on Kyiv
Artillery - Unitary
Excalibur has 5kg of explosive fill and was designed, among others, as a tank killer. Because it's GPS guided, it will be best used against parked tanks (to allow for good target identification, input of coordinates and such) but direct hit from 155/152mm howitzer, 122mm Grad or maybe even 120mm mortar should be pretty damaging to a tank in any case. Close hits might not destroy tank outright, but might strip ERA, cope cage, optics, or even throw a track or damage engine with fragmentation, so it's not nothing. If heavy artillery hits cope cage and it detonates on impact, there's still heavy fragmentation that can punch through the thinnest armour, so cope cage will be probably ineffective in this case. This type of artillery was responsible for destroying most of tanks and other vehicles during initial Kyiv push
Artillery - BONUS
This thing uses two skeets that seek for tank with IR sensor or mmwave radar and plunge an EFP down on it. Because it's not initiated on impact, cope cage is useless here.
Artillery - DPICM
Each DPICM element contains small shaped charge that is supposed to penetrate some 70-100mm of steel. This is vastly more than on top of any tank and it should result in penetration. ERA on top can protect against DPICM; because DPICM detonate on impact, if cope cage gets in the way, jet of copper will disperse before reaching turret. However if DPICM element falls on engine or driver compartment, that is where cope cage doesn't extend, tank will be still disabled. Cope cage is partially useful here
Artillery - FASCAM
This thing deploys minefield anywhere you point your 155mm howitzer at - right in front of enemy, right behind enemy, somewhere around so they have to change plans or are forced in some killzone, or even directly at them so now they have to navigate through suddenty appearing minefield. Because these mines attack bottom and sides, cope cage is useless here
RPGs
Slat armour is useful against some of the older, more common RPGs, but most of the time soldiers using it are on the sides, not on top of tank. A couple of hits with RPG-7 can disable some of older tanks. Because urban combat against tanks didn't happen, cope cage is useless here.
Other tank
Top of tank is usually not exposed to other tank, and if it is, it means that either tank is on the side or you're fighting against flying type 59. Either way, something went horribly wrong. Cope cage is useless here
Drones - FPV
These things are basically very cheap and limited ATGMs with superior maneuverability, and these can hit tank where armor is thinnest - from back or sides, bypassing cope cage entirely. Cope cage is useless here
Drones - Bombers
Drones have been reported to drop RPG-7 warheads, DPICM elements, RKG-3 grenades and more. All limitations of DPICM apply. Cope cage is partially useful here
Drones - Lancets
Some Ukrainian howitzer positions are protected by metal nets, because it was discovered that Lancets brake and stop on them without detonating. Because chicken wire is much less visible than cope cage, russian AT team might send a Lancet against it not recognizing that it will be ineffective. It seems to work against some of russian AT weapons, so it was also installed on some of tanks
like this. Yes it's Chally 2
It's probably mildly effective, but only against some threats, and you still will have a bad day if someone has ATGM, RPG with tandem charge or accurate tube artillery
I don't know why i have written this, but there's a chance I might do it again. If you don't want to see this content, convince me to stop
okay i see now
