Improvement of the convergence of the time domain electromagnetic inverse method by using the PSO algorithm

In this paper, we propose a method for modeling the electromagnetic disturbances. This proposed method is based on the coupling between the electromagnetic inverse method in the time domain and the PSO optimization tool. In order to avoid measurement errors, the proposed method was applied to a near field cartography calculated through analytical expressions that describe the magnetic radiation of simple elementary dipoles. To evaluate the contribution of the proposed method, we compare the results obtained using the PSO algorithm with those given by the temporal inverse method based on genetic algorithms. The comparison between the results given by these two approaches has shown that the inverse temporal method based on the PSO is very robust in terms of convergence and simplicity of implementation.
