Abstract: Theoretical analysis of a vertical broadside symmetrically coupled
strip line assuming TEM propagation mode is presented in the paper. The
effective dielectric permittivity and characteristic impedance of the analysed
strip line is determined applying the Equivalent Electrodes Method (EEM), and
the results are compared with the ones obtained using the Finite Element Method
(FEM). The paper shows determination of the closed-form Green's function of
uniform charge per unit line length placed in an anisotropic medium between two
parallel infinite grounded plates. Additionally, dielectric permittivity tensor
has a diagonal form, and both, even and odd, modes are considered.
