EMP and how to protect systems against it.

Can the stealth technology protect systems against some EMP pulses? The answer is no. Or it depends on. The power of the EMP. If stealth. It can make those electromagnetic waves slide over the structure without. Inducting electricity into the structure. It can protect electronics. But if the EMP can slip into the structure. The Stealth is useless. 

All EMP systems. They are not nuclear-based. If technology can deny the EMP from reaching the microchips. It could deny their destruction. But even if a low-voltage surge. It can destroy the programming of the microchips. 

There are plans to use extremely high-power radio systems. To create the EMP fields to protect targets against the stealth fighters. The system uses impulse capacitors to create an EMP that can damage a stealth fighter’s electronics. The system uses a Marx-generator-based EMP system. That gives an EMP impulses as a series of pulses. There is suspicion that the former Duga radar (”The Soviet Woodpecker). It is also used for EMP tests. Also, there were suspicions that Duga was planned to be used as a jammer. Or the Loran type navigation system for Russian bombers. 

Duga station entered service in 1976. The Duga station was supposed to shut down after the “Chernobyl” nuclear disaster. But it continued its service until December 1989. 

The Duga system. It was one of the most powerful radio transmitters in history. The system could be used in many types of tests. The EMP role, and the role as the transmitter of the subliminal infra-sound-based propaganda, or psychological operations. It is possible, but purely hypothetical. There is almost certainty that the Soviet military and the KGB conducted this type of research. But did they use the Duga radar for that purpose? That is a different thing. 

The question in this case is. About things like whether the EMP can reach the targeted electronics. Things like. The Faraday cage. And. Optical-fiber-based technologies. Can protect the  systems more effectively. The optical fiber-based technology means that the computer microchips are inside the Faraday cage. The Faraday cage is helpless. If the EMP travels in the cage from the electric wires. The EMP protection. It must be made by using systems that disconnect the wires. When they see a nuclear explosion. The flash of the explosion activates the switch. That disconnects the system. 

"A 400-kilometre-high (250 mi; 1,300,000 ft) EMP: gamma rays hit the atmosphere between 20–40 km (66,000–131,000 ft) altitude, ejecting electrons, which are then deflected sideways by Earth's magnetic field, over a large area. Because of the curvature and downward tilt of Earth's magnetic field over the US, the maximum EMP occurs south of the detonation and the minimum occurs to the north." (Wikipedia, Nuclear electromagnetic pulse9

“A Faraday cage or Faraday shield is an enclosure used to block some electromagnetic fields. A Faraday shield may be formed by a continuous covering of conductive material, or in the case of a Faraday cage, by a mesh of such materials. Faraday cages are named after the scientist Michael Faraday, who first constructed one in 1836.” (Wikipedia, Faraday cage)

The problem is this. The EMP can be made by making a surge into the wire. This means that the system. It doesn’t send a light flash in every case.  The capacitor-based EMP doesn’t require the explosives. The NNEMP (Non-Nuclear EMP) can be the next-generation tool for the military.  It can shut down electronics. Just before the commando strikes. The NNEMP system. That. Uses coherent radio waves (Radio masers) can also send the EMP pulses through the Faraday cage. The system must aim the radio waves through the holes of the metal net. Another way is to use a drone that shoots an electric wire through the EMP protector. When the EMP system sends an impulse. That electric wire conducts the EMP pulse into the EMP-protected room.  

And information travels between those microchips in optical fibers. That makes the system more immune to the EMP. The key question in EMP protection is this. Can the EMP affect electronics? Or can it touch electronics? The problem with traditional computers is their wires. The EMP inducts. A high voltage in those wires. And that damages microchips. The Faraday cage can protect computers. 

Only if the cage is fully separated from the outer space. Any wire or antenna that crosses the cage transfers the EMP into the cage. The reason why those EMP pulses are so hard for defenders is that. They have such a large-scale wavelength. That. Making a jammer against those systems is very  hard. To make. The jammer should cover all the wavelengths. That the EMP involves. And its power must be very strong. There is theoretical research. About things like counter-EMP. But the problem is that the nuclear-based EMP is so strong. And the EMP. That turns incoming EMP away must be launched precisely at the right moment. The problem is that the EMP is a radio wave. That scatters from every direction. 

The problem with the EMP pulse is that it destroys microchips very effectively. The protective system. It can be based on the idea that the computer is in a Faraday cage. The sensor system communicates with it wirelessly by using laser communication. Another way is to offer the EMP pulse a route past the sensitive electronics. The system can use the superconducting wires. That offers the route to the electromagnetic field. The wire itself is in the Faraday cage, which means it will not send electromagnetic radiation into its environment. 

If that kind of system can be made. It can also conduct the radar impulses away from the transmitter. The idea is that the system forces the radio waves to travel in the desired direction. The best way to protect buildings against the EMP is to enclose them in a Faraday cage. The metal cage. That surrounds. The house can protect electronics against the EMP. The sensors and the internet. It can work by using laser communication or optical fibers through the walls. 

If EMP destroys the sensor or router. The crew can take a new one outside. But that requires. That the house be completely surrounded by the Faraday cage. The system must also use power sources that are inside the house. One single wire. That which is not protected can conduct the EMP inside the protective cage.   But there is always a possibility that a drone lands on the roof of the house. Drills a hole in the roof. And drops the electric antenna inside it. Then the system can conduct the EMP pulse into the house.
