Software for the analysis of 3-D devices formed by several rectangular waveguides with different axes, connected together through a central parallelepiped lossless cavity

In this communication, a commercial CAD software to analyze and optimize 3D multiport waveguide devices is presented. The program implements the generalized admittance matrix (GAM) method for the analysis and a hybrid optimizer based on genetic algorithms (GA) and the gradient method, for the optimization. The part dealing with the optimization has been previously developed by RYMSA Co., where they are using it for the optimization of a number of electromagnetic problems. It is important to point out that this software has a broader range of application, in the sense that, since the two parts (analysis and optimization) can run independently to each other, the optimizer can be used to solve any kind of parametric optimization problem.
