原文是:
Initial values for the parameters l1 and l2 can be set to be 入/4, where 入 is the wavelength at the center frequency for a partly substrate-filled waveguide. The wavelength 入 can be calculated, e.g., with the transverse resonance technique or with an electro-magnetic structer simulator.
最后一句话说明了这个可以用CST算出来,,不过不管用什么方法,只要能算出来就教我把!

是不是波导波长?
freespace里面的波长乘以传播常数
传播常数等于1除以根号下介质的相对介电常数
freespace的波长是光速除以频率
比如2G下是150mm,介电常数为4.5的FR4材料,大概是70.7的波长了。
好像CST macro里面可以算,自己找找吧,calculation里面
但是是partly filled哦,不完全填充的!
