Abstract: A stationary microwave system for irradiating microwave frequency energy 200-40 GHz) at target vehicles disrupts the operation of the target vehicle's electronic engine control systems, rendering it incapable of fleeing law enforcement agents (LEAs). The system includes a microwave generation source; a triggering system to control pulsewidth, periodic frequency, duration, and time on; an interlock system for safety; and a delivery system for directing the microwave energy and irradiating the target vehicle. The parameters of the microwave energy are optimized by the system such that the radiated microwave energy has the characteristics required to disrupt the target vehicle.

Abstract: A gaseous electrode for a magnetohydrodynamic (MHD) generator is positioned in a primary magnetic field. Single or multiple openings or slots are provided in the electrode from which a gaseous plume or plumes may be emitted into the main MHD channel depending on whether one or more than one opening is provided. The openings or slots are normally oriented parallel to the magnetic field, but can be at an angle to the magnetic field. The electrode is formed having an inter cavity which is continuously filled with an ionizable inert gas. Microwave or RF energy is radiated into the cavity to ionize the gas thereby generating an ionized plasma source from which a gaseous plasma plume may be formed. The plasma plume is injected into the MHD generator's main channel thereby forming a gaseous electrode. The electrode is oriented in the main channel opposed by at least a second electrode which may be of the same or a different configuration.
