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