In this thesis, we use an on-line measurement method to study the parameters measurement for the double-circuit transmission lines which is based on the transmissionlineEquation.
In this paper, basic transmissionlineequation and four kinds of lumped-circuit model were constructed according to transmissionline theory, microwave network, antenna theory and matrix theory.
