If you were thinking that shields used in Star Wars for protection against laser attacks is just science fiction then you need to have a reality check as those shields are very much possible to be made.

Researchers from the University of Leicester have designed a concept for fully operational deflector shields. As per the physicists, the technology behind the shield is quite feasible and in fact, the skill behind the principle is already in use.

Researchers explained the phenomenon that the Star Wars deflector shields are like force shields around an object that deflects laser belts. Scientists worked on an assumption that if an object is surrounded by a field of very hot plasma that has been kept intact with the help of an electromagnetic field then it would also act like deflector shields.

Moreover, it would be very important to focus on the plasma. If the plasma would be denser then higher would be the frequency of electromagnetic radiation to deflect. As said earlier that such science already exists, researchers cited an example of earth's own ionosphere.

Ionosphere is plasma extending from 50km above earth's surface to the edge of space. "Just like the plasma described in our paper, it reflects certain frequencies of electromagnetic radiation, in this case radio frequencies", affirmed researchers.

The method could be used to send communications over the horizon as there radio transmissions are unable to reach normally. There are certain problems in the concept. Firstly, to hold the plasma in place, it is required that magnetic field should be quite strong.

Secondly, the shield deflects electromagnetic radiation that includes light. It means that whosoever would be inside the shield would be unable to see anything outside.

To overcome the problems, researchers said another method could be used and that is trap radiation inside plasma rather than excluding it.
