The article presents an efficient iterative method for analysing non-linear photonic crystals. The new approach is used for analysing a frequency converter constructed with a 2D pillar-type photonic crystal waveguide structure. The considered converter uses the non-linear properties and the compound waveguide structure. The analysis is based on the iterative resolution of two relationships between incident and reflected volume-waves. The reflection operator is expressed using Hankel functions. Numerical results have been obtained with moderate CPU time and memory requirement. Simulations obtained are in agreement with recent published results. © 2010 Taylor & Francis. Source

In this article, the theory and numerical algorithm of a periodic wave concept iterative method are presented for the analysis of periodic structures of metallic via-holes. The method is based on the transverse wave formulation using the periodic boundary conditions to extract the single via-hole's impedance. As application a substrate integrated waveguide structures are studied. © 2011 Wiley Periodicals, Inc. Source
