Abstract
A novel rank‐revealing shielded‐block preconditioner that accelerates the iterative integral‐equation‐based analysis of wave propagation in electromagnetic crystal (EC) devices is presented. The proposed shielded‐block preconditioner exploits the bandgap character of the background electromagnetic crystal in order to achieve both rapid convergence of the iterative solver as well as a low matrix‐vector multiplication cost. The versatility and computational efficiency of the shielded‐block preconditioner are demonstrated by its application to the analysis of wave propagation in a defectless electromagnetic crystal along an electromagnetic crystal waveguide and out of an electromagnetic crystal horn antenna array. © 2006 Wiley Periodicals, Inc.
