Analyzation of EMP coupling to multi-conductor transmission lines based on the over-relaxation iterative methods

The distributed analytical representation and iterative technique (DARIT) has been proposed for the calculation of electromagnetic pulse (EMP) radiated field coupling to multi-conductor transmission lines (MTLs). At first, this 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 which adopt the over-relaxation iterative methods have been developed as well. This paper compares these four methods from the points of view of the accuracy and convergence speed, etc.
