具有圆形电壁边界的纵向磁化旋电波导在非对称模式下具有分裂极限TE截止数和简并极限TM截止数。磁壁波导显示出简并的极限TE和极限TM截止数。这些结果是由有关平面电路的特征方程直接导出的。证明了电壁和磁壁互换的旋电和旋磁平面结构存在双重特性。测量的谐振频率进行了比较与理论模型的一些旋磁装置。
ABSTRACT Longitudinally magnetized gyroelectric waveguide with circular electric wall boundaries exhibit split limit-TE cut-off numbers but degenerate limit-TM cut-off numbers for non-symmetric modes. The magnetic wall waveguide displays degenerate limit-TE and limit-TM cut-off numbers. These results have been deduced directly from the characteristic equations of the related planar circuits. The existence of dual characteristics between gyroelectric and gyromagnetic planar structures with electric and magnetic walls interchanged are con finned. Measured resonant frequencies are compared with theoretical models for some gyromagnetic devices.
