[QUOTE="puregenius_91, post: 2098147, member: 749903"] Mark, The best resource you are looking for is well... not yet written. The shield that you see in space show is, as of today, fictional. It can absolutely not exist. At least none that can be applied to any general particle in space or on earth. It may be possible for magnetic materials. How? well, assume this shield was created of "layers' of magnetic 'sheets' with each sheet having opposite polarities. Now when some unmagnetized object (say an iron bullet), but which is made of magnetic material, enters the first sheet, it is induced with a polarity opposite to that of the first sheet's magnetic direction (let's just assume it is north). But when it reaches the next sheet, it would be repelled, because the sheet would be north, and north magnetic field would repel the north facing bullet. This is in theory, possible. if you had a strong magnetic field. The same can be applied for electrically charged particles... say protons, electrons. But for a neutral, nonmagnetic atom (which is what most of the world is made up of) there is no known way of creating a 'force field'.
