  MODE 中的Eigenmode Expansion (EME) solver 一开始就有端口这个物件，参见这个说明。
  
  FDTD 也经常用来计算器件的参数，包括波导系统和超材料等效折射率提取等，因此新版也添加了这个物件 Ports，它包括 mode source模式光源、field monitor场监视器和mode expansion monitor模式分解监视器。其中平面波原则上也可以认为是均匀介质中的模式，所以超材料仿真也可以使用。因为它已经包含了模式光源，因此一般情况下仿真文件就不需要另外添加光源了。
  
  要添加端口这个物件，直接点击
  
  即可，它会自动位于FDTD里面，所以需要在添加仿真区后才能添加。
  
  顶层的组名ports不能修改，即使GUI上看起来能修改；但是该组下面的每一个port都是可以改名字的。
  
  网上大部分使用S参数的例子都换为Port啦，例如
  Ring resonator FDTD (final parameter extraction)
  Microstrip with a Lumped RLC element
  Quarter-wave transformer
