Can OpenEMS find far-field electric field phase information at unit radius? #73

Discussed in https://github.com/thliebig/openEMS-Project/discussions/72

Originally posted by **XDAChen** May 19, 2023 I want to obtain information about an antenna's far-field phase change relative to its phase center at a unit radius, r using OpenEMS. In HFSS I had done it with far-field result --> rE --> cang_ang. I am not sure if openEMS can provide the same information. While I am looking at the nf2ff documentation, if I understand correctly, I set my antenna's phase center as default [0,0,0], and I can compute the electric field strength at a radius r. If it is a complex number I can post-process the complex field strength to find the angle, which would be the phase shift relative to the antenna phase center? Anyone had done a similar thing before?
