Abstract

This paper proposes a circuit network analogue for the solution of Maxwell's equations in differential form for two dimensional domains. First an equivalence is established among the electric and magnetic field and the corresponding voltage and current in the equivalent network. The proposed equivalent circuit cell consists of resistances, inductances and capacitances. Independent and controlled voltage/current sources are used to implement circuit models for radiating sources and boundary conditions. Standard circuit techniques and simulators are used to solve the resulting network in terms of voltages, currents and their corresponding field's variables. In the paper, some applications are given about the analysis of linear and nonlinear two dimensional shielding structures. The results and CPU time are compared with those given by a dedicated finite differences code. The advantages of this approach are shown and its limitations discussed
