Subscriber老师好,因为看到这张帖子的图,有点困惑,我得到的数据是折射率n和吸收系数k,不知道图中的k代表什么

Ansys Employee这里是折射率实部为n和虚部是k,后者不是常说的吸收系数,因为没有与波数相乘呢。
需要注意的是,同一个符号在不同情况下的代表的意义可能不同。这个文件头已经说明了它们的意义。
当知道折射率实部和虚部后,就可以直接输入到材料库中了,参见 Ansys Insight: 如何找到材料库中没有的材料折射率,并输入到软件中?

Subscriber那如果我只有折射率n和吸收系数k的数据呢?可以将吸收系数换算到折射率虚部吗March 4, 2022 at 3:34 pmGuilin Sun
Ansys Employee可以啊,参见这个 Working with lossy modes and dB/m to κ conversion 实际上这个转换就是将复折射率乘以真空波数得到传播常数,实部代表波矢,虚部就是振幅吸收系数。你斟酌一下。 需要注意,不同人所说的吸收系数可能代表不同含义,有的就是指折射率虚部,有的是指功率吸收系数,较少直接给出振幅吸收系数的,你要注意看看有没有单位。没有单位很可能就是指折射率虚部,要自己斟酌。March 5, 2022 at 1:26 amoylllc
