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.

“…The considered theory on the transient radiation of dipoles is presented in [49][50][51][52][53][54][55][56][57][58][59][60][61][62]. The principle of this method is mainly based on the plane wave spectrum (PWS) transform associated with the fast Fourier transform as introduced in [63][64][65][66][67][68][69][70][71][72][73][74][75][76][77]. We realize here a space-time computation method enabling to map the EM NF in a plane situated at certain distance of the given 2D NF data in time-domain as proposed in [63][64][65][66][67].…”

This paper deals with the processing method of electromagnetic (EM) near-field (NF) radiated by microwave circuits with transient pulse signals. Two different NF processing methods are proposed by applying the time-frequency approach. First, a computation method of NF/NF transform is presented. This enables to calculate the EM NF maps at different distances from the radiating circuit. The feasibility of NF/NF in both frequency-and time-domain is verified with experimental results. Then, NF processing based on NF emission model implemented in UWB frequency band is also examined in the second part of the paper. For that, the number of EM NF maps representing the large band model is reduced in order to simplify the model based on a set of dipole-array. The timedomain model is implemented by considering the convolution of the transient excitation signals and the UWB dipole-array model. This time-frequency model was validated with a planar microstrip device excited by microwave signal modulating 1.25-GHz-carrier and 0.5-GHz-bandwidth. The methods explored in this paper are particularly useful for the investigation of time-domain emissions for EMC applications by considering transient EM interferences (EMIs).

“…To do this, one employs the space-frequency transform theory known as the plan wave spectrum (PWS) method. As introduced in [25][26][27][28][29][30][31][32], this spacetransform is exactly similar to the fast Fourier transform in two-dimension domain.…”

Abstract-This article deals with the development of computation method dedicated to the extraction of the transient EM-near-field at certain distance from the given 2-D data for the baseband application up to GHz. As described in the methodological analysis, it is based on the use of fft combined with the plane wave spectrum (PWS) operation. In order to verify the efficiency of the introduced method, a radiating source formed by the combination of electric dipoles excited by a short duration transient pulse current with a spectrum bandwidth of about 5 GHz is considered. It was shown that compared to the direct calculation, one gets the same behaviors of magnetic near-field components H x , H y and H z with the presented extraction method, in the planes placed at {3 mm, 8 mm, 13 mm} of the initial reference plane. To confirm the relevance of the proposed transform, validation with a standard commercial tool was performed.In future, we envisage to exploit the proposed computation method to predict the transient electromagnetic (EM) field emissions notably in the microwave electronic devices for the EMC applications.
