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.

Embedded electronic systems, used in automotive field, have been improved to meet a wide range of users needs. The integration of different electronic components which handle different tasks enables to achieve this target. To upgrade the performance of these systems, a lot of attention must be brought to electromagnetic interferences between these components. Therefore, models are needed to predict the radiated emission of these devices and the possible coupling between them. This paper presents an approach used to model the crosstalk between electromagnetic (EM) radiated fields and a transmission line placed in its vicinity. The proposed modeling procedure enables to predict the coupling even in the case of mismatched transmission lines.

“…Parametric modeling of I/O ports from measured transient responses has been addressed in [1] and the modeling of power supply ports is addressed in [2,3,4]. In this paper, we demonstrate those methods by developing models for both I/O and power supply ports for an high-speed IC memory, that is a 512Mb NOR Flash memory in 90nm technology produced by Numonyx.…”
