电场强度数值

      老师,您好! 我看文献(第一张图)里用E/E0表示电场增强,其中E为模拟结构的电场,E0为真空环境电场,那么FDTD模拟出的电场强度数值(第二张图)是否就是E/E0,还是说需要进一步处理才能得到E/E0?

      如果你没有做其它设置,FDTD缺省的频域监视器结果就是与光源归化的后的。

      孙老师您好,您能给出通过FDTD进行电磁场仿真的结果,求|E/E0|的四次方的具体教程吗?

      |E/E0|的四次方可以对强度再平方:

      E2=getelectric("monitor");

      E4=E2^2;

      当然前提是光源振幅为1(正常情况)。
