Variability Analysis of a Non-Uniform Transmission Line Using Stochastic Galerkin Method

In this paper, we propose a technique which estimates statistical information of electrical properties of a transmission line that has a variability in shape by using a polynomial chaos method. A conventional Monte Carlo method requires enormous time to calculate the statistical information, since it performs a huge number of numerical analyses by stochastically changing the shapes of the transmission lines. In the proposed method, by means of a stochastic Galerkin method, which is one of the polynomial chaos methods, the statistical information can be obtained by performing the analysis only once.
