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 circuits. A thin-wire time-domain integral formulation based on the antenna theory is used to calculate both conducted current due to a voltage generator and induced current due to an electromagnetic perturbation. A special numerical treatment is used for angular points and multiple junctions in the electric circuit. The voltage source can be inserted in the model. Nonlinear components, such as diodes or transistors, are described under their high frequency behavior
