Combining EM accuracy with the speed of analytical models for simulation of arbitrary passive microwave components

An automated circuit-modeling tool is developed for arbitrary passive components. The tool builds compact, parameterized, analytical models based on full-wave EM simulations. The scattering parameters (or the transmission line parameters) of the components are stored as a multidimensional function of frequency and geometrical parameters. The modeling algorithm combines adaptive data selecting and modeling techniques. The circuit models guarantee EM-accuracy and generality, and circuit simulation speed and flexibility.
