【摘要】 从弯曲波纹波导中广义耦合波方程出发，进行数值优化迭代，得到在８ｍｍ波段，ＴＥ（０１）—ＨＥ（１１）高功率高效率模式变换器的设计。计算中考虑了金属壁所带来的欧姆损耗，并采用了相位重匹配技术以提高转换效率。给出了一组优化设计尺寸及计算结果。更多还原

【Abstract】 Based on the general coupled wave equations in corrugated circular waveguides with axial curvature,this paper employs a numerical optimization method to get the design of 8mm TE(01)-HE(11)high efficiency mode converter.Some factors such as the ohmic losses of the waveguide wall and the phase rematch techniques are taken into account. Finally,a set of optimized size and its calculation results are given.更多还原
