Abstract :
A new approach using the moments of field amplitudes has been applied for phase-correcting mirror synthesis of a 110-GHz gyrotron internal mode converter. The synthesized mirrors have smooth profiles in contrast to the mirrors synthesized using the previously employed iteration method. The design has been checked using a physical optics propagation code with the result of a Gaussian output amplitude at the gyrotron window position.
