Hi,<\/p>\n

I am trying to simulate the MOKE rotation and ellipticity of a periodic array of Ni NPs. I followed this article<\/a> to set up my simulations and took the Kerr rotation from the polarization ellipse analysis group. I use a BFAST plane wave incident at 0 or 10 deg, 45 deg polarization angle, periodic boundary conditions along x and y, and PML along z. Compared to the 0 deg incident plane wave case, I obtained Kerr rotation values 40 times higher at certain frequencies. I wonder, could this be an artifact due to my choice of boundary conditions, position of the analysis group, or something else?\"\"<\/p>\n
