Previously, i have managed to make shields for air craft that use protons to collect around 'incoming things' and deflect them. this is a new advent of nature, if you ask me, as this i cannot think of a natural occurrence of in the world. it would be like a tin film, circling the craft, then would all condense as incoming rounds would come towards it. now, i want to make hand held shields like that.
Basically, we would need a 'aura of particles,' that collect around the incoming projectile. this would mean that it is like a plasma ball around the protected area, using electromagnetism to focus on any metals that are incoming, or, a field that has a diameter of a few feet, with the 'plasma' free flowing around the area's outside. this would lead to a "star wars" type drone shield, of course.
