A coaxial cable has an inner conductor of radius a = 0.8 mm and an outer conductor of radius b = 2.6 mm. The conductors have σ_c = 5.28 x 10⁷ S/m, μ_c = μ_o, and ∈_c = ∈_o; they are separated by a dielectric material having σ = 10^–5 S/m, μ = μ_o, ∈ = 3.5 ∈_o. At 80 MHz, calculate the line parameters L, C, G, and R.
