| 摘 要： | 本文从理论上证明:当截止波导口上纵向磁场不为零时,磁波将导致波型耦合,这种耦合还将随着截止波导长度的改变而周期变化.从而解释了截止波导或截止波导滤波器存在有限工作频率范围的原因.为了消除或减弱截止波导的波型耦合,需要对截止波导进行特殊的设计.

| Abstract: | It is theoretically shown that magnetic wave will result in mode coupling when its longitudinal magnetic field is nonzero in the openning of a waveguide, this coupling will periodically vary with the length of the cut-off waveguide, and thereby interpret why working frequency range of a cut-off waveguide on a cut-off waveguide filter is limited2,3]. In order to eliminate or reduce this coupling, a special design on cut-off waveguide is needed. |
