Abstract: A device for generating and radiating radio frequencies. The device includes a transmission line, a source, and a means for applying a voltage impulse to the transmission line from a low impedance source. A quarter-wave trap is added between the source and the transmission line to suppress the onset of a parasitic radiating mode. The quarter-wave trap also acts as an antenna to transmit the energy to the surrounding environment from the transmission line, which is behaving as an oscillatory circuit. The low impedance source is an electrically driven impulse generator. As a further modification, a second antenna can be attached to the free end of the transmission line to enable lower frequencies to be transmitted.

Abstract: A device for generating an intense radio frequency pulse through use of a helical Magneto-Cumulative Generator (MCG). The MCG provides a chemical explosion and acts as a converter to transform the chemical/mechanical energy into an electrical energy impulse. Due to the detonation/combustion process, a vortex wake is produced which assumes the role of a quarter-wave trap/antenna. If the MCG is in high velocity flight, a bow-shaped shockwave, followed by a second shock front, is established around the head of the MCG, becoming a second antenna. Without flight, two MCG's are placed head-to-head so that the vortex wakes emit in opposite directions. Since the explosion destroys the MCG, a model is created to perform multiple tests of the ability of an MCG to act as an RF device.
