9 The MIT Photonic-Bands (MPB) package is a program for computing
10 the band structures (dispersion relations) and electromagnetic modes of
11 periodic dielectric structures, on both serial and parallel computers. It was
12 developed by Steven G. Johnson at MIT in the Joannopoulos Ab Initio Physics
14 This program computes definite-frequency eigenstates of Maxwell's
15 equations in periodic dielectric structures for arbitrary wavevectors, using
16 fully-vectorial and three-dimensional methods. It is especially
17 designed for the study of photonic crystals (a.k.a. photonic
18 band-gap materials), but is also applicable to many other problems
19 in optics, such as waveguides and resonator systems.
20 (For example, it can solve for the modes of waveguides with arbitrary
