The MIT Photonic-Bands ( MPB ) package is a free program for computing the band structures (dispersion relations) and electromagnetic modes of periodic dielectric structures, on both serial and parallel computers. This program computes definite-frequency eigenstates (harmonic modes) 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.) As complementary Meep package works for time-domain simulations, reflection/transmission spectra, etc. (MPB is frequency-domain; Meep is Time-domain.) There are two common computational approaches to studying dielectric structures such as photonic crystals: frequency-domain and time-domai...
