Cross¶
This example computes light propagation of incident plane waves (at oblique angle of incidence) through an isolated cross:

Cross geometry¶
Note
As the geometry of this setup exhibits two mirror symmetries the computational domain is reduced to a quarter domain (at higher numerical efficiency).
In a first post process, the Fourier transform for the upper half space is computed (output file transmitted_fourier_transform.jcm
). In a subsequent post-process OpticalImaging
this Fourier transform is mapped to image_fourier_transform.jcm
modelling the light transfer through the optical system (as defined in the post-process OpticalImaging
). You can use a Cartesian export post-process to compute the so formed coherent image. The following figure shows the image in different -slices (image planes displaced along
-direction), for
-polarized illumination.
