This paper presents a new algorithm based on Integrated Congru-ence transform for the analysis of both uniform and nonuniform transmission lines. The key advantage of the proposed algorithm is that constructing a spanning orthonormal basis for the space-dependent moments is done without computing these moments ex-plicitly. The proposed algorithm thus carries the numerical effi-ciency of Krylov-based projection techniques of lumped RLC net-works to the domain of the distributed transmission line networks. The proposed algorithm can be used to construct an orthogonal ba-sis for any set of moments related through a differential operator
