I use the diagonal refractive index of materials with dispersion and loss. When setting the FDTD or RCWA, I use light source with z direction and back emission, corresponding to the nx, ny, nz of the materials to the setting x, y, z axis in lumerical.<\/p>\n<p>The problem is that I cannot get a correct result till I define nz&#8217;=nz, and ny&#8217;=ny, exchanging y and z axis basically. I am confused to this result.&nbsp;<\/p>\n<p>Maybe I am wrong at some points.&nbsp;<\/p>\n<p>Could anyone help? I am happy to talk or set a zoom meeting.
