Effects of Directed Energy Weapons is an encyclopedic treatment of how Directed Energy Weapons work, how the energy of these weapons is propagated to the target, and how the weapon/beam-target interaction creates effects (damage) in the target. This is a technical exposition, written at the undergraduate physics and engineering level that could serve either as a text book or as a reference text for technical practitioners. The text addresses Kinetic Energy Weapons in addition to Lasers, Microwaves and Particle Beams.
