Latest Patents

Zawada holds a patent for a "Crossed-field amplifier bias circuit and method for improved starting." This invention discloses a crossed-field amplifier that features an anode and cathode, along with a pair of permanent magnets. These magnets create a magnetic field that is perpendicular to the electric field established between the anode and cathode. The electric bias circuit connected between the cathode and a power supply typically provides energy to an oxygen source within the amplifier. This bias circuit is designed to supply a negative DC voltage to the cathode. After the amplifier is turned off, the DC bias retains electrons within the interaction area between the cathode and anode, facilitating a quick restart of the amplifier.
