✦ Synopsis

A finite-difference time-space numerical algorithm for the analysis of transient electromagnetic fields is proposed based on the expression of the field vectors in terms of vector potential functions. The method allows for both integral and finite-difference ( ) calculation of the potential functions PF . Both approaches can be applied in combination. Since it is based on the time-domain integral-equation approach, it reduces the 3D problem to a 2D one, and only the tangential vector potential components are involved in the calculation. The consistency of the method has been proved by simulations of Gaussian pulse propagation in a homogeneous and an open-end microstripline and a thin-plate scattering problem.

## Abstract This Letter, proposes an algebraic domain decomposition algorithm (ADDA) to solve large sparse linear systems derived from the vector finite‐element method (FEM) for 3D electromagnetic field problems. The proposed method segments the problem into several smaller pieces, solves each subp
