摘要：

In this paper, a numerical study of direct TM(01)-TE(11) mode converters in highly overmoded, bent smooth, circular waveguides is presented for high-power millimeter waves. The various shapers of bent waveguides are elaborately chosen, and their optimized geometrical dimensions have been achieved with a general optimization code employing the coupled mode theory. The mode converters designed can have high conversion efficiencies over 98% and wide bandwidths of 28%.
