Aegis Shielding Matrix, often abbreviated as ASM or even AS, is an energy-shielding technology discovered almost 40 years ago on Telios Prime . By focusing field emitters so that they intersect their fields in a cumulative effect, rather than a cancellation effect, it becomes possible to precisely control how permeable these fields become to matter and energy of specific wavelengths. By rapidly varying the exact phase of each emitters specific field (within the confines of the equation that maintains the cumulative effect), it became possible to quickly disperse the energy of impacts (both matter and energy based) on any point of the matrix.
