An efficient numerical scheme was introduced for calculating the field at the interface of an 2D electromagnetic band gap (EBG) or periodic artificial material. The periodic artificial material consisted of a periodic structure made of layers of conducting cylinders. An analysis of the branch point singularities in the complex wavenumber plane allowed for a determination of the physical properties of the field. The calculations confirm the asymptotic field behavior.
