RCWA_Stochastic_Optimizer

Stochastic Optimization with rigorous-coupled-wave-analysis (RCWA) Basically a brute force type optimization whereby we generate a large set of structures, simulate them, evaluate how close they are to our desired objective, trim the population based on this objective, and then 'mate' the good structures to generate a 'fitter' population. Repeat until good.

API Definition

'layered_structure_class' specifies a single individual

1. num_layers

2. lattice_constant

3. frozen_unfrozen_layer_bool %freezes a layer in the optimization

4. layer_dielectric_tensors= cell(1); %specifies dielectric tensor for each layer %every dielectric tensor is a 3x3 matrix % each cell element is a cell array with one tensor for each medium

5. layer_structures = cell(1); %specifies grating of each structure

6. layer_thicknesses = cell(1);
