      请问如何看结构不同的衍射级啊

      这个简单,你可以用VIsualizer,选farfield,再选10个周期,远场投射即可。

       

      如果要准确的角度和透射率,则需要用脚本,参见

      孙老师,您好,我想问下关于脚本farfield函新里的周期数这个参数的具体含义,看您上面说可以改变周期数来获取仿真结构的行射级,但里面的周期数这个参数不是用来扩展仿真结构的面积的吗?官网上这个函数关于这个参数解释也不是特别具体,所以想问下这个参数的具体作用或含义是什么? 麻烦孙老师解答一下谢谢。

      farfield函新里的周期数这个参数是为了近似得到所谓的周期结果,不是严格准确的,只是为了看衍射级。精确的算法是Grating函数。
