Efficient and accurate full-wave analysis of the open-ended coaxial cable

Abstract

An efficient implementation of the full-wave open-ended-coaxial-line analysis is presented in this paper. The involved integrals are approached in such a way that the admittance is accurately calculated. Moreover, the calculus time is noticeably reduced. This technique is particularly useful when repeated analysis are performed as occurs, e.g., when measuring permittivity.
