Subscriber我想获得材料在x方向的折射率与透射率和相位的关系,所以想使用sweep参数扫描的方法获得,但是在材料的设置处,只能看到index和index unit,请问特定方向上的折射率变化可以怎么设置啊

Ansys Employee特定方向上的折射率是说这个是各向异性吗?
确认是各向异性的,参见
Ansys Insight: 用于设置如何设置光学各向异性材料?
如果没有色散,你需要在MODEL或者结构组中设置折射率参数,施加到指定结构,然后扫描这个参数。你需要用脚本设置。 我测试虽然下列脚本无误:
nx=1.5; (此句仅作测试用,你需要设置变量nx,然后扫描它。)
setnamed("rectangle","index",[nx,1.4,1.5]);但是并不能改变折射率,因为里面的折射率现在是字符类型。
能做的就是设置nk 材料,选择为各向异性,再设置。例如
setmaterial("MyMaterial", {"Refractive Index": [nx,1.3,1.5], "Imaginary Refractive Index": [0,0,0.1]});
但是,当材料在使用中一般是不能修改其参数的,因此,你需要先将结构中选的材料改为其它,然后再修改,再赋给这个结构。
具体怎么用脚本修改结构的材料,你可以参考结构组中的例子,请花点时间学习一下。
