Shaped cathodes enhance key magnetron performance parameters, such as output power, power efficiency, and impedance. Simulations using these novel designs showed a dramatic increase in the range of magnetic field in which the magnetron functions, a doubling of output power, an increase in efficiency, an elimination of mode competition, and a halving of the start-up time.
