Abstract
A plasma antenna generator includes an ionizable material, an explosive charge capable of projecting the ionizable material upon detonation, and a detonator coupled with the explosive charge. An electromagnetic pulse transmitting system includes an electromagnetic pulse generator and a plasma antenna generator capable of reradiating an electromagnetic pulse emitted from the electromagnetic pulse generator. A method includes providing an explosive device comprising an ionizable material, detonating the explosive device to propel the ionizable material, and ionizing the ionizable material to form at least one plasma trail. A sensing system includes an electromagnetic pulse generator, a plasma antenna generator capable of reradiating an electromagnetic pulse emitted from the electromagnetic pulse generator, and a sensing system capable of receiving and analyzing at least a portion of the electromagnetic pulse after being reflected from an interface.
