BlochCode

Registered 2011-10-07 by Felix Lawrence

Among other functions, BlochCode lets you efficiently calculate reflections off many PC stacks. It does this by calculating a PC's Bloch factors (complex band structure) and impedance from electric and magnetic field data.

This field data can be produced by COMSOL another EM solver, or potentially by experimental near-field data. COMSOL templates for square/rectangular and triangular lattice PCs are provided. Also included are functions to calculate reflection and transmission matrices from impedances, for arbitrary stacks of PCs.

BlochCode is written in Python; it requires SciPy and NumPy to be installed, preferably as part of Sage.
