§8.模式耦合理论在无源网络中的应用所谓无源网络即指不包括电子注的各种微波网络,如波导(简单或复合的)、周期性加载慢波线、定向耦合器、微波滤波器以及其它各种微波元件等。利用模式耦合理论对无源网络的分析已在很多文献中发表过。虽然模式耦合理论并不能代替求解电磁埸分布的繁杂数学计算,但这种分析方法的主要特点在于通过 §8. The Application of Mode Coupling Theory in Passive Networks Passive networks refer to various microwave networks that do not include electronic charges, such as waveguides (simple or complex), periodic loading of slow-wave lines, directional couplers, microwaves Filters and other various microwave components. Analysis of passive networks using mode coupling theory has been published in many literatures. Although the theory of mode coupling can not replace the complex mathematics for solving the electromagnetic field distribution, the main characteristic of this method is that by
