Extraction of Inductance Parameter for Nonuniform Transmission Line in Anisotropic Dielectric

Since the inductance parameter of nonuniform transmission line in anisotropic dielectric is difficult to extract and the tensor dielectric permittivity is hard to solve, a novel method is proposed in this paper to solve this problem. It uses filament division to establish the dispersion model of nonuniform transmission line, and develops the Ampere loop integral dyadic equations and closed circuit dyadic impedance matrix equations in frequency domain based on electromagnetic quasi-static. Finally the inductance parameter is solved. The new method are applied to the calculation of nonuniform transmission line models filled in free space and anisotropic dielectric, showing accuracy and validity of the proposed method. Moreover, the new method can be applied to various transmission line structures and different anisotropic dielectric.
