Study of nonuniform coupled transmission lines based on maxwellian circuits

In this paper, study of nonuniform coupled transmission lines is analyzed with the generalized transmission line equations (GTLE). The GTLE, including static parameter(L, C) and dynamic parameter(α, β), can describe the microstrip circuit very well. Its parameters are extracted from the full-wave solutions(such as MOM and FDTD). So the circuit model made up of the parameters is named as Maxwellian Circuit. The maxwellian circuit is a kind of circuit while it comes from full-wave solutions. So it build an convenient bridge between field and circuit. It´s convenient for circuit engineer to deal with the circuit parameter rather than full-wave solutions. The study is validated in comparison with the current obtained from GTLE and MOM solutions.
