TEM analysis of coupled strip lines with anisotropic substrate

摘要

Theoretical analysis of a coupled strip line assuming TEM mode propagation is carried out in the paper. The effective dielectric permittivity and characteristic impedance of a transmission line is determined applying Equivalent Electrodes Method (EEM). The Green's function of the uniform charge per unit line length placed in an anisotropic media between two parallel plates is used and tensor for dielectric permittivity having diagonal form, and even and odd modes are considered in both paper.
