Freeware to compute near-to-far field transformations for radiative and guided waves

Light emitters or scatterers embedded in thin-film stacks may couple energy to both free-space plane-waves and guided modes of the stratified structure. Researchers at LP2N have elaborated a free-ware that allows to compute the free-space and guided radiation diagrams with a high accuracy from the sole knowledge of the near-field around the emitters or scatterers.
