Rigorous full wave analysis of complex planar circuits affords a fine discretization mesh, which results in a large eigenmode spectrum. To reduce the modal complexity, a new method of lines approach is presented, which combines discretization lines in longitudinal direction with the concept of localized and accessible modes. Additionally, an innovative individual interface meshing is introduced, which is especially suited for cascaded circuits with strongly varying lateral dimensions. The computation time is significantly decreased by these two complexity reduction steps. Perfect accuracy and high efficiency are demonstrated for two cascaded CPW filters.     «
