在电磁学和通信工程中,波导这个词可以指在它的端点间传递电磁波的任何线性结构。但最初和最常见的意思是指用来传输无线电波的空心金属管。这种波导主要用作微波频率的传输线,在微波炉、雷达、通讯卫星和微波无线电链路设备中用来将微波发送器和接收机与它们的天线连接起来。
同时,电磁波导的辛分析也是构造对偶有限元的理论基础。
Moreover, symplectic analysis for electromagnetic waveguides provides the theoretical basis for constructing dual finite element method (FEM).
本文基于对偶变量变分原理,参照矢量基有限元的构造,提出了电磁波导的对偶棱边元。
