When I want to set an anistropic (n,k) material the new material does not take the refractive index values, but has only the values of 1, 1, 1. Also, I get the error “The material property, Refractive Index was not set. The property value must be a string or a matrix.”<\/p>\n

I use the following python script to set the material:<\/p>\n

\n
n_GaN = [2.4869, 2.3, 2.4869]<\/div>\n
material = “GaN”<\/div>\n
mode.setmaterial(mode.addmaterial(“(n,k) Material”), “name”, material)<\/div>\n
\n
\n
mode.setmaterial(material, “Anisotropy”, 1)<\/div>\n
mode.setmaterial(material, {“Refractive Index”: n_GaN, “Imaginary Refractive Index”: [0, 0, 0]})<\/div>\n
 <\/div>\n
Here, “mode” is defined as: <\/p>\n
\n
mode = lumapi.MODE()<\/div>\n
 <\/div>\n
Do I have to define the values in anbother way?<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"template":"","class_list":["post-363896","topic","type-topic","status-closed","hentry","topic-tag-anisotropy-2"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
