Matrix elements of Γ₀ (x = 0) and Γ_L (x = L) as functions of the distance d₁₃ between lines 1 − 1′ and 3 − 3′. Two different circuits equivalent to symmetrical (Fig. 3) and asymmetrical (Fig. 1) circuits are used. The distance between lines 1 − 1′ and 2 − 2′ is d₁₂ = 0.02 m in each circuit. The length and radius of the three lines are L = 2 m and 0.5 mm, respectively. The values of the resistances are R₁₂ = 50 Ω, R₂₃ = 5 Ω, R₁₃ = R₂₃ = 300 Ω, and R₁₂′ = 349.715 Ω, which is equivalent to the characteristic impedance between lines 1 − 1′ and 2 − 2′(=Z_nn).
