Since the 1980-ties, the asymmetric mains impedances have been defined by IEC CISPR 16–1–2 [1] and used in an artificial mains network (AMN) suited in the frequency range (10) 150 kHz to 30 MHz. The mains impedance has recently been extended by the definition of asymmetric or common-mode artificial networks (AAN) and coupling/ decoupling networks (CDN) which are defined to be used in the frequency...
In this work a full-wave method based on the Mixed Potential Integral Equation technique is used to analyze the propagation in the time domain of a differential signal for a coupled microstrip structure with a metallic top cover. This top cover may be due to a dense circuit packaging or it can be intentionally added to enhance the immunity of the guiding structure. We study the impact of low-frequency...
Shielding of electromagnetic transient fields requires a correct vision of the coupling mechanism and of fundamental aspects of victim functionality and susceptibility. Suitable parameters for the measure of the shielding efficiency are necessary in case of typical transient fields like ESD and classical the information provided by the shielding effectiveness as defined in IEEE-Std.299 may be not...
Localization algorithm for stochastic EMI sources based on time domain planar near-field scanning of tangential electromagnetic field components emitted by a complex radiated structure is presented. The main theory aspects of the field reconstruction in the object plane as well as the main limitations for scanning parameters are also discussed for the proposed localization procedure. The autocorrelation...
