How can I get the phase shift as a function of the rotation of a nanofin when circularly polarized light is applied?
Can I use the s_parameters or need to use another analysis?
This is related to the geometric phase (Berry phase) in meta-atoms.<\/p>\n

To simulate a circularly polarized source, I added a plane wave source with a 90-degree polarization and a 90-degree phase shift. I did this within the S-parameters analysis. I’m unsure if this is the correct approach for performing a parameter sweep, or if the additional source should be placed outside the S-parameters analysis.<\/p>\n

How can I obtain the phase as a function of optimization parameters, such as the angle of rotation of a nanofin?
Note: In the figure, I have a circular pillar but I replace it with a rectangular one.<\/p>\n

Thank you for your help.<\/p><\/div>\n
