MULTEM 2: A new version of the program for transmission and band-structurecalculations of photonic crystals

We present a new version of a program for the calculation of the frequency band structure of an infinite photonic crystal, and of the transmission, re flection and absorption coefficients of light by a slab of this crystal. Th e crystal consists of a stack of identical slices parallel to a given surfa ce; a slice may consist of a number of different components, each of which can be either a homogeneous plate or a multilayer of non-overlapping spheri cal particles of given periodicity parallel to the surface. The homogeneous media to the left and right of the slab may be different (have different r eal and positive dielectric functions and magnetic permeabilities). (C) 200 0 Elsevier Science B.V.
