Introduction

Most of the features of PWE band solver were demonstrated in Lessons 11 and 12.

In this tutorial we apply the solver to a 3D problem of a fcc (face centered cubic) and diamond lattices of spherical air balls suspended in a dielectric medium. Such structures have been intensively studied in the past [2]. The fcc structure is known to lack a full photonic bandgap, whereas the diamond lattice, as first reported by Ho, Chan and Soukoulis in 1990, have a complete photonic band gap.
