metaprop_multi_objective

repository update. Added metaprop_fibermode_doublet_sym.py which implements a constrained optimization enforcing mirror symmetry about the x and y axes. Mirror symmetry can be exploited in this problem since the target mode has such symmetry. Each metasurface has effectively a quarter of the degrees of freedom compared to the unconstrained problem.

metaprop_fibermode_doublet_ego_sym.py

introduced a setting to fix the maximum diameter of metasurfaces. Practically this is translated into an additional constraint on the optimization algorithm that fixes to zero the degrees of freedom that are outside the designated region. Overall, the number of pixels does not change to guarantee sufficient padding for the fft. Added metaprop_fibermode_doublet_ego_sym.py that implements the ego optimization for finding the optimal distance values under mirror boundary conditions.
