Generating radius matrix of desired metalens phase profile Choose desired phase profile and find corresponding radius of the meta-atom.
The input data should have radius-transmission and radius-phase relations. You can use RCWA, FDTD,...etc to calculate the relation.
- Setting parameters in the input.json(transmission & phase data, lens size, radius & height range and step)
- For the 1st run, set a breakpoint at line 60. You need to customly determine the range of the radius.
- After determining the radius range, just follow the pop out dialog. Note that if you choose "custom", the input desired phase matrix should have values between 0 to 2pi.
