Edoardo Vergerio 625cd64f53 implemented new filtering system based on a Filter Class. Previously, filtering was made expensive by extreme padding, now this has been fixed by choosing a more appropriate padding size. The gradient chain based on unitcells has been implemented but the results have yet to be tested using FDTD, which will be the next step. Added some utilities to visualize the effect of filter radius on given input masks and added all data concerning unit cell simulations. Still to be done is to fix materials in the MEEP simulations, so as to account for true material behavior instead of relying on constant refractive indices.

sorter_to_gauss.py

added mpid support for three layer stacks. Added sorter_to_gauss as example usage of the three stack.

sorter_to_ident.py

implemented and did some testing about applying a conic filter on phase masks. This should smooth out outliers at the cost of a possible reduction of total overlap efficiency. Several example devices have been added for testing purposes.

test_gres.py

added test_gres.py as a first attempt at implementing a cavity based metasurface. It uses a stacked metasurface setup as a hotstart for a subsequent optimization of the cavity phase parameters. Effectively, a folded setup is convenient for the reason being that no alignment of subsequent masks is required.

testing_mode_sorter.py

scripts for testing usage of the mpid class. Shaping the inverse design algorithm into a class has proven useful to streamline the design process. Being more easy to handle, one can now test various devices with very little setup effort.
