High-Accurate Numerical Computation of Internal Impedance of Cylindrical Conductors for Complex Arguments of Arbitrary Magnitude

In this paper, a numerical model is proposed for computing the per-unit-length internal impedance of tubular cylindrical conductors for complex arguments of arbitrary magnitudes. The proposed model either numerically solves the exact formula for internal impedance consisting of modified Bessel functions or utilizes asymptotic approximations of modified Bessel functions when applicable. It is shown that the results obtained by the proposed model are highly accurate and numerically stable. The proposed model is also applicable for solid cylindrical conductors.
