“…Facing to the complexity of modern electronic architectures and systems, the issues related to the unintentional electromagnetic compatibility interference (EMI) becomes one of critical embedded equipment malfunction sources (Vye, D., 2011) (Yang, T., et al, 2010). In this optic, deeming with functional features of automotive vehicles, several electronic components and printed circuit board (PCB) can be seriously unsafe (Archambeault, B., et al, 2010) (Kopp, M., 2011) (Liu, K., 2011) (T, Hubing., 2011.…”

For the safety and reliability of modern hybrid electronic systems in function of the increase of complexity and density integration, relevant modeling methods of near-field (NF) radiation are necessary. This article develops a time-frequency modeling method of electromagnetic (EM) NF emitted by electronic devices excited by transient pulse current. The modeling method is originally flexible to fast switching disturbances propagating in the mixed-systems. The model is based-on the ultra wide band (UWB) model of EM NF maps using a set of elementary EM dipoles. An innovative algorithm for generating a simple reduced model is established. Then, by considering the convolution between the signals exciting the circuit and the UWB model introduced, transient radiation models are realized. The method developed was validated with the magnetic NF radiated at some mm above the microstrip planar DUT. The UWB model effectiveness was verified in RF baseband from DC to 100 MHz. Then, NF map time-dependent model emitted by the circuit excited by a microwave signal modulating 0.9 GHz carrier with 0.6 GHz -1.2 GHz frequency band is also validated. As expected, good agreements between simulations, measurements and the models investigated are observed for any form of excitation current.

“…But the 3D full-wave method requires large number of memories and longer computing time. In recent years, several authors have proposed the hybrid method [12][13][14][15][16], i.e., the co-simulation of combining the full-wave method and commercial simulation software (such as HSPICE and ADS). In these attractive methods, the field coupling effects are analyzed by full-wave technique and incorporated into the simulators for co-simulations.…”

Abstract-This paper presents an extended delay-rational macromodel for electromagnetic interference analysis of mixed signal circuits. Firstly, an S-parameter matrix based delay-rational macromodel of the associated microwave network or system is established. Then, we extend the macromodel to include the external electromagnetic interference effects. The forced waves induced by the excitation fields are computed using full-wave method and treated as additional equivalent sources. Next, the macromodel is modified to embed the additional sources at each corresponding port. Finally, the resulting macromodel is converted into equivalent circuit for circuit analysis with the corresponding linear and non-linear port terminations. Several examples are computed by using the proposed method and the numerical results are compared with those obtained by 3-D FDTD method only. They are all in a good agreement that validate this method.

“…With the increase of the integration density of the modern electrical and electronic systems, the analysis of electromagnetic interference (EMI) and electromagnetic compatibility (EMC) issues become one of the primary importance and unavoidable step during the design process [1][2][3][4][5][6][7]. This effect can be found in various stages of the different chains for example in the automotive vehicles or aeronautic engines [8][9][10][11][12].…”

Abstract-A modeling of the metallic wires susceptibility facing to the disturbances caused by electromagnetic (EM) near-field (NF) radiated by electronic structures in radio frequencies (RF) is introduced by using a hybrid method. This latter is based on the use of the given EM-data calculated or determined from the standard computation tools associated with basic analytical methods expressing the coupling voltages at the victim wire extremities and the EM-NF radiations. In difference to the classical methods based on the far-field radiations, the main benefit of this method lies on the possibility to take into account the evanescent waves from the disturbing elements. The basic principle illustrating the hybrid method principle is explained. To verify the relevance of the method proposed, we consider a metallic wire having cm-length above the ground plane disturbed by the EM-near-waves from the electronic circuits in proximity. For that, we model the EM radiation of the disturbing electronic circuits and then, apply the hybrid method to evaluate the coupling voltages induced through the wires. By considering the radiations around hundreds MHz, we demonstrate that the hybrid method proposed enables us to generate voltages in good agreement with the simulations performed with the commercial tools. Two types of realistic configurations are studied. First, with a microstrip loop circuit radiating at about 0.7 GHz, we calculated induced voltages at the extremities of the structures. Then, the same analysis was made with a 3D-model coil self for the large band from 0.1 GHz to 0.5 GHz. The results are in good accordance between the terminal voltages of the wire. The relative error in the second configuration falls less than 10%. This investigation is important for the EM compatibility (EMC) analysis of the radiating coupling between wires and complex electrical and electronic systems disturbed by RF harmonics.
