This plot is obtained with the kerr_attribute grid attribute enabled. The same analysis with the magnetized surface in MOKE.fsp will show that the reflected light becomes elliptical polarized. 17 likes, 1 comments - Ed Gilkison (edgilkison) on Instagram: Debbie in California sent me the Lucas magneto off her rigid MAC, after last years Summer. This plot is obtained by disabling the kerr_attribute grid attribute. (This plot can be generated by clicking on "Run analysis" under the Analysis script tab of the Polarization Ellipse analysis group). As expected, the polarization of the reflected field does not change. We will use a a simple anisotropic material (with nx = 1.55, ny = 1.45, nz = 1.5) as a test case (see MOKE_reference.fsp). The polarization ellipse analysis object can be found in the object library In MOKE.fsp, we start with a plane wave polarized in the x direction, and use Polarization Ellipse analysis group to determine the primary polarization angle and the degree of circular polarization. The script MOKE.lsf defines U and sets it as the transform matrix, where U is obtained from the method described on this page, Matrix transformation $$ U=\frac\right) $$Īnd use a matrix transform grid attribute to apply this rotation. To do this, we define the following unitary matrix: Specifically, we want to set the magnetization vector perpendicular to the reflection surface and parallel to the plane of incidence. iMagneto es una aplicación sencilla y gratis (gpl) solo disponible para Mac, que se encuentra en la categoría Sonido de la subcategoría Emisoras y Streaming. In this example, we will use an anisotropic material combined with a grid attribute object, which allows us to apply an arbitrary unitary matrix necessary for inducing the correct rotation. Other types of MOKE (with the magnetization vector along different directions) can be modeled with a very similar simulation methodology. In this example, we study a simple polar MOKE set up where the magnetization vector perpendicular to the reflection surface, and the incident plane wave is at normal incidence. In this example, we model the Magneto-Optic Kerr Effect (MOKE), which describes the changes to light reflected from a magnetized surface.
