Edoardo Vergerio 367ffc3457 modified metaprop_fibermode_doublet.py with the introduction of an utility function to compute the input field by propgating the source field of a desired propagation distance. This is useful in simulations when setting up custom sources. Added full_meta.ipynb which implements the full first metasurface, truncating the substrate with a custom source and computing the fields just before MS2 using projection monitors

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.
