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-vectar multiplication cost. The versatility and computational efficiency of the shielded-block precondlitioner 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.
