MNPBEM is a toolbox for the simulation of metallic nanoparticles (MNP), using a boundary element method (BEM) approach developed by F. J. Garcia de Abajo and A. Howie, Phys. Rev. B 65, 115418 (2002). The main purpose of the toolbox is to solve Maxwell's equations for a dielectric environment where bodies with homogeneous and isotropic dielectric functions are separated by abrupt interfaces. Although the approach is in principle suited for arbitrary body sizes and photon energies, it is tested (and probably works best) for metallic nanoparticles with sizes ranging from a few to a few hundreds of nanometers, and for frequencies in the optical and near-infrared regime.

On this page we provide papers describing the toolbox, the MNPBEM toolbox, and the help pages. A new version of the toolbox MNPBEM13, which has been published in Comp. Phys. Commun. 185, 1177 (2014), includes classes for EELS simulations and can be downloaded below. This new version additionally includes mirror symmetry and corrects several minor bugs of the first release.
