Abstract

In this paper a theory on the non-uniformity of characteristic impedance of coaxial cables with helical corrugated inner-and outer-conductors is proposed. From a model of conductors with slowly varying quasi-circular section

by means of the domain variational ap-proach and Riccati equation

the approximate analytic expression for calculating the characteristic impedance and the voltage reflection coefficient are derived. Many problems on cable design

manufacture and connection are analysed.
