Description
This resource contains the raw spectra and code with examples how to synthesize and characterize the disordered structures used in investigations. In the sim_data.zip file the first folder, (reflectance/) contains the raw spectra R1-384.dat (in ASCII format) for reflectance simulations with refractive index of n=1.5. The lookuptable_reflectance.xlsx spreadsheet contain the corresponding Minkowksi values. Files R385-524.dat contain the spectra for structures with n=1.1 and n=2.6.
In the the second folder (transmittance_meanfreepath/) the files T525-1941.dat and TE_525-1941.dat contain the transmittance and the ballistic transmittance spectra for the mean free path simulations, and the details are provided in the lookuptable_transmittance.xlsx spreadsheet.
lam.dat contains the corresponding wavelength values for all the raw spectra.
The code.zip contains a struct_synth/ folder for examples (Matlab files *.m) on how to simulate, analyse, and export disordered structures. The minkowski/ folder has an example python code how calculate the Minkowski values. Finally the fdtd/ folder contains examples how to import structures to Ansys Lumerical FDTD simulation software.
