Can we someday make the protective field like in some SciFi tales?

The solution could be found from the ion cannons or laser fields. If incoming ammunition will load by using opposite polarity than ions, it would pull incoming ions or electrons to it. 

One of the easiest ways is to make the protective field is simply to use the drones, which are flying around the protected target. The mission of those drones is to block incoming ammunition and they can also use active systems like microwaves or some kind of lasers for blocking the ammunition. The system can use DEW (Directed Energy Weapons) because their ammunition capacity is unlimited. In some versions, the drone would have the radio-system that makes the electric arc to the point, where it's targeted.

 Or in some ideas, the radar would load the plus mark electricity to objects, that is approaching the target. Then the cathode rays will send through the air, and high-energetic electrons or minus mark ions will terminate the incoming ammunition. The plus-polarity will pull those ions to the incoming ammunition and that thing makes the possibility to defend against the incoming ammunitions. 

The fact is that if we are using extremely hot holograms, we might create a limited area, where the material objects are unable to pass. The idea is is that the temperature of the holograms can increase by using the same frequency of radiation and pump the energy into the hologram. In that case, the temperature of the hologram increases, and the thing that makes the ability to limit the area of the hologram, what makes the energy field start suddenly is also possible to make.

An energy field system requires that around the protected target would be the drones, whose mission is to send the counter radiation to the infrared hologram bubble. The system can create a steep-edged edge to that infrared zone. The idea for that thing is taken from the Stanislaw Lem book "The Invincible", where the form of the protective field would be created by using the radiation that is coming from the craft, and the robots, what are standing on both sides of the bubble. 

That theoretical thing can be made by using modern existing technology. The infrared hologram layer can turn very hot if its energy would increases by using the outcoming radiation. And in that system is also possible to connect the lidar system what tells if something touched the energy shield. 

'The idea is that the hologram will set in the wanted form by pressing it by using the counter radiation, which has a similar frequency with the laser ray, which creates the protective hologram field. Inside that field can be made powerful wind what mission is to break the melted ammunition and turn then away from the surface of the target. 

The force of the ion cannons can turn away simply by using the ion field, which has the same polarity as incoming ions. And the protection against the laser rays can make by using steam, or rather saying supercooled water or ice dust, what temperature is extremely low. That thing would suck the energy from the incoming laser rays.
