Reply To: How to find the polarization of the electric field at the far-field?

[ph23resch01002]

Hi Sir,

I am following the metalens example provided on the Ansys Lumerical website to generate a vortex beam at the focal plane z = 20 μm. Using a DFT monitor at  Z = 20 μm to observe the vector fields would be computationally expensive. In the metalens example too, the far-field projection has been used to obtain the intensity profile. I would like to get an intensity profile with polarization as shown in the figure below.

 

Is there any other way to get the polarization plot other than using a line or field monitor at the focal plane?

Thank you,
