Text and notes a The important conclusion to be drawn from this discussion is that Maxwell's equations present a unified theory of analysis for any system at any frequency, provided we use appropriate simplifications when the wavelengths involved are much larger, comparable to, or much smaller than the circuit dimensions ■从以上过论中可得如下重要结论:当系统的波长与电路尺 y批比大的多小多,或相比纵时,只要进行适当的 篇化,麦克斯新韦方程就可欢任何频率下的任何系统提供统 一舵分析理论。 上海海学信息工程学院上海海事大学信息工程学院 Text and notes ◼ The important conclusion to be drawn from this discussion is that Maxwell’s equations present a unified theory of analysis for any system at any frequency, provided we use appropriate simplifications when the wavelengths involved are much larger, comparable to, or much smaller than the circuit dimensions. ◼ 从以上讨论中可得如下重要结论：当系统的波长与电路尺 寸相比大的多、小的多，或者相比拟时，只要进行适当的 简化，麦克斯韦方程就可对任何频率下的任何系统提供统 一的分析理论
