H.A.R.O. FIELD or H-Field - short for hyper anti-beam repelling orb, it is a beam energy dispersal field generated intended for defense against beam energy-based weaponry. This technology is featured in some mobile suits and mobile armors in the fan fiction MS GUNDAM: The Lost War Chronicles.
When Minovsky particles are released into the air or into open space, the positive and negative particles spontaneously align themselves into a three-dimensional cubic lattice. Due to the repulsive and electrostatic forces between the Minovsky particles, this lattice functions as a kind of a force field, which is referred to as an I-field. This field has difficulty permeating conductive materials like metal, water, and plasma, and it exerts a repulsive force against mega particles. An I- field is used to to deflect enemy mega particle beams. Due to its high power requirements, the I-field generator originally could only be installed in large mobile weapons. When the generator is activated, the I-field forms an invisible barrier around the mobile weapon, protecting it from incoming beam attacks. However, this barrier has no effect against solid objects like missiles and projectiles, and beam weapons can still be used at point blank range within the barrier's boundary. A weakness of the I-field is that the generators tend to overheat and thus force cooldowns.
The H-Field follows the fundamental theories and characteristics of its predecessor, the I-Field. H-Field, on the other hand, functions by dispersing and forming Minovsky particles into an array of expanding spherical pulses that can be adjusted in terms of area span. By continually dispersing the particles into spherical pulses, an orb-like field is generated that negates beam-based weaponry. This method greatly reduces wear and tear on the power generators, thus overheat and cooldowns were diminished as well.
