Abstract
A high-power relativistic magnetron wherein the cathode geometry is shaped to form a DC electric field that has a non-negligible azimuthal component causing preferential selection of the pi mode at startup (suppression of mode competition), a significant increase in radiated power output and time integrated efficiency when compared to standard relativistic magnetron cathode designs.
