How would energy shields Work in real life?

Essentially, if you can wall yourself off with plasma, it can be used to deflect electromagnetic radiation, like a directed energy weapon (a laser or something similar). You flip it on, and sure enough, lasers bounce right off. However, the shield works equally well in both directions, so you can’t return fire either.

Will energy shields ever be possible?

No. “Energy shields” are, essentially, “the forces between atoms but we take the atoms away”. About the only way we can conceive to do this is not to take the atoms away – make “shields” out of steel or concrete or similar stuff. Energy shields are, essentially, plot devices in science fiction.

How would a plasma shield work?

The technology — which use a laser to create a curtain of miniature plasma explosions like firecrackers to turn away an enemy — could be adapted to turn it into a physical shield, capable of warding off projectiles. (Tracking a missile nose with a laser is exactly what laser infra-red countermeasuresdo at the moment.)

How does a forcefield work?

It is not intended to protect against projectiles, radiation, or energy weapons such as lasers. The field purportedly works by using a combination of lasers, electricity and microwaves to rapidly heat up the air creating a field of (ionised) superheated air-plasma which disrupts, or at least attenuates, the shock wave.

Are Forcefields possible?

Although the force fields used in science fiction may not conform to the known laws of physics, there are still loopholes that might make the creation of such a force field possible. First, there may be a fifth force, still unseen in the laboratory.

Could force fields exist?

The ‘force fields’ used in space opera do not exist. Hypothetically, new ‘fundamental’ forces have been discovered in the fictional universe where the story takes place. These fields have whatever properties are necessary to carry on the story. These probably don’t exist, but no one can yet be sure.

Is electromagnetic shield possible?

Well, in a sense any kind of hard surface is an electromagnetic shield. It is possible to shield very well against some types of electromagnetic radiation. For example, putting a cell phone inside a “Faraday bag” will block enough radio waves from reaching the cell phone that it can not receive incoming calls.

How does an energy shield work?

That is, an “energy shield” is electromagnetic, with no other reasonable choice. With “contact”, you can still avoid walls by spraying small particles out. The corona effect uses electric charges to accelerate charged particles which then smash into other particles, pushing them away.

How does a plasma shield work?

The electromagnetic force keeping together the molecules of the shield is what takes care dissipating the energy of the weapons. Plasma Shields are the closest thing to energy shields that modern science understands.

What is the point of shielding?

The idea of shielding that’s not simple walls is useful for constant renewal rather than wearing out, and being stronger than mere matter.

Can plasma shields block kinetic attacks?

No current shield can block a kinetic attack directly because solid matter is not meaningfully affected by a plasma shield pulse; however, if your setting prominently features energy based small arms such as a plasma pulse, laser, radiation, or electrolaser weapons those could certainly be blocked with existing technologies.
