Modeling of electromagnetic radiated emissions in electronic devices by equivalent sources based on HGAPSO method

This paper presents a modeling methodology to characterize electromagnetic emissions radiated by an electronic device. Based on the replacement of the real device by an equivalent dipole network, these dipoles must be able to generate the same radiation near field of the device under test. The parameters of the dipoles are determined using a fast and stable optimization method, Hybrid (HGAPSO) [1] involving genetic algorithms (GA) [2] and the particles swarm optimization method (PSO) [3].
