QPMS
Electromagnetic multiple scattering library and toolkit.

The utilities are located in the misc
directory. Run the utility with h
argument to get more info.
These scripts deal with simple 2D rectangular lattices, finite or infinite, one scatterer per unit cell. \( D_{2h} \) or \( D_{4h} \) symmetric adapted bases are used where applicable.
