A new numerical formulation in time-domain analysis of thin-wire structures

We present a new numerical method for determining the time dependent current distribution on thin-wire structures excited by an arbitrary time-varying field. The method is based on the solution of the electric field integral equation (EFIE) for thin wires and is shown to be stable at large times. It also enables the treatment of wire junctions by only applying slightly modified basis functions at the end of the wires.
