Where

μ₀ = 4*3.14159265359 x 10^-7

μr = Relative Permeability of the medium

∈₀ = 8.856 x 10^-12

∈_r = Relative Permittivity of the medium

R = Outer radius of wire

r = Inner radius of wire

C = capacitance per unit length

L = inductance per unit length

Z = impedance per unit length

f_c = Cut-off frequency

*NOTE - Consider μr = 1 for non-magnetic medium, which may not be the case always.
