Study of conduction and induction phenomena in electric circuits using a time-domain integral formulation

This paper deals with the modeling of the susceptibility of electric circui ts. A thin-wire time-domain integral formulation based on the antenna theor y is used to calculate both conducted current due to a voltage generator an d induced current due to an electromagnetic perturbation. Special numerical treatment is used for angular points and multiple junctions in the electri c circuit. Voltage source can be inserted in the model. Non linear componen ts, such as diodes or transistors, are described under their high frequency behavior.
