Prediction of EMP coupling to multi-conductor transmission lines with the over relaxation analytical iterative methods

The Distributed Analytical Representation and Iterative Technique (DARIT) is proposed in this paper for the calculation of electromagnetic pulse (EMP) radiated field coupling to multi-conductor transmission lines (MTLs). Traditionally, the technique adopts the Jacobi iteration scheme (Jacobi- DARIT-field) or the Gauss-Seidel iteration scheme (Seidel-DARIT-field). More recently, based on these two methods, the JOR-DARIT-field and SOR-DARIT-field methods have been developed as well. This paper compares the four methods from the perspectives of accuracy and convergence speed, etc.
