The automated approach to the mode-matching and S-matrix techniques: from idea to realization

An attempt of combining the efficiency of problem-oriented numerical algorithms with the generality of mesh methods is made. The automatic procedure of decomposition of complicated waveguide structures is developed. It takes into account peculiarities of the given problem (symmetries, uniformity and so on) and tries to find out the best possible solution. Presented approach is successfully applied to create the electromagnetic simulator Microwave Desktop 2 (MWD 2). It allows one to solve a wide range of electromagnetic problems from analysis to optimization.
