Optical Tamm Modes

We made some notes while familarizing with Tamm modes, electromagnetic surface modes that exist at the interface of periodic systems. We develop the teory for the modes at the interface between a periodic superlattice and a homogeneous system, implemented it in Perl and PDL and tested the code on the interface between a dielectric superlatice and vacuum. The notes are here.
