Abstract :
This paper uses precise integration method in time domain (PITD) to simulate the electromagnetic transient behavior of the long nonuniform transmission line. The matrix exponential integrator is computed using Krylov subspace method, and a scaling method is proposed to reduce the iteration times of the Arnoldi process.
