Expansions with coefficient algorithms for time domain responses of skin effect lossy coaxial cables

Time domain ste p res ponse expansions with coe ffi cient algorithms are de veloped from the system fun ction of a doubly termina ted skin effect lossy coaxial transmission line. Three models of series impedance valid for (a) high frequency, (b) high and intermediate frequen cy, (c) high and low frequency , are in corporated into the system fun ction. The system fun ction is ex panded via the method of polyno mial expansions of analytic fun ction s through generating relations and inve rted term by term into the tim e domain throu gh the inverse Laplace transform.
