multipole decomposition of dielectric nanoparticles in an array

Juan Luis Garcia, CSIC

These files of COMSOL and MATLAB make the calculation of the electromagnetic fields for a hexagonal array of Silicon hemispheres over a dielectric (mesoporous titania) array of cylinders with the same arrangement over a base layer of the dielectric on top a silica substrate.
The multipole decomposition of the particles is made and the surface energy and reflectance are calculated.

1.Download the files from (exceed the limit here)
2. Create a folder called C:\datacomsol\
3. Change the geometric and materials parameters if you want.
4. Run the COMSOL files (v.5.5) (_RF for Radiofrequency module or _WO for Wave optics module).
5. Clear all the tables in Tables.
6. Evaluate all the derived values.
7. Export all the data in Export.
8. run Matlab file (v.2010b).
