Â Greetings of the day sir! In the metalens example, There are three parameters. They are period, height, and radius. The period is fixed as 0.35 micrometer and the parameter sweep is done for two parameters height and radius. After performing the parameter sweep, height is fixed too, the radius is varied to get the phase shift ranging from 0 to 2*pi.

In my case, I get a Transmission peak for LCP light at 1658nm wavelength for the dimensions of the meta atom. At this wavelength, I changed the orientation of the meta atom from 0 to 180 degrees, I got the phase shifts from 0 to 360 degrees. However, the Transmission coefficients vary drastically. So I want to optimize the other two parameters w1 and w2 along with theta values. In the metalens example, they have fixed the height and varied only the radius to get the appropriate phase shifts and constant transmission coefficients. In my case, what if I want to choose different w1 and w2 values along with theta values to get the phase shifts along with the high transmission coefficients?

Is nested sweep the only way?Â Â
