Abstract-This paper presents a new simulation methodology to study the effect of radiated transient disturbances on digital communication systems. The procedure is divided in two stages. In the first one, FDTD numerical simulation is used to determine the transient levels coupled to the antennas. In the second stage, these levels are analyzed by means of a signal processing simulation software to determine the degradation caused in the system. The procedure is applied to a DAB system in car when a radiated interference is generated by a transient in a vehicle cable. The results show that the amplitude of the radiated transient coupled signal is a key parameter, but it is also essential to take into account other parameters such as burst duration and frequency.

“…Once again, quite good correlations between the results from the method proposed and CST simulations are found. Compared to the computation tools and the methods indicated in [77][78][79][80][81][82][83][84][85][86], it is noteworthy that the computation methods established in this paper, we have benefits in terms of the simplicity and the execution time of the algorithm. Furthermore, the method presented here does not depend on the complexity of the structure under consideration.…”

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).

“…This efficient and rapid method of analysis is ideal for most signals. However, previous studies have identified some problems when applying the IEEE-FSV [22] to analyse particular signals [35], [37], [38]. In order to overcome these drawbacks and to make a correct validation, a variation of the IEEE-FSV method has been developed [39], [40] and is known as FSV-UPC [41].…”

Abstract-Electromagnetic analysis of hydropower generators is common practice but there is little emphasis on studying the effect of rotor whirling in the analysis. This paper demonstrates the use of the unbalanced magnetic pull (UMP) curves based on purely dynamic eccentricity motion for a wide range of whirling frequencies in the prediction of the steady state UMP in the case of mixed eccentricities motion. The latter motion type is more realistic in practice. Actual electromagnetic (EM) simulations are also carried out for these mixed eccentricities motion cases in order to verify the proposed method. Good agreement between the UMP from the actual EM simulations and the UMP predictions are made when low eccentricities exist. The proposed method is thus very useful since firstly, very few EM software packages can handle mixed eccentricities motion and secondly, since actual EM simulations of intricate rotor centre motion are time-consuming, the proposed method is a big time saver. A modified feature selective validation (FSV) method, the FSV-UPC, is also applied to assess the similarities and the differences in the force computations.Index Terms-eccentricity, electromagnetic simulations, hydropower, rotor, whirl
