We present in this paper an overview of conducted and radiated sources that could be considered as potential intentional electromagnetic interference (IEMI) sources against critical infrastructures associated with power systems. The sources are classified according to the commonly addressed criteria in IEMI. In addition, to assess their potential risk, reported IEMI sources are classified according...
A differential transmission line bend generates a large common mode due to its asymmetry, and it leads signal integrity problems. In this paper, the imbalance difference model, which was proposed by the authors for estimation of common-mode radiation, is extended to apply to the differential signaling systems. An equivalent circuit model based on the imbalance difference model is proposed for estimation...
Inductive power transfer (IPT) systems typically employ a relatively pure sinusoidal primary current. The frequency of operation is chosen to not interfere with existing LF systems such as RFID transponders. Rectification combined with filtering on the secondary side of an IPT system necessarily introduces significant harmonic content into the secondary current as well as ringing, in some cases. Although...
A simple method based on equivalent dipole modeling is used to characterize the emissions from within a metallic enclosure with apertures. Planes surrounding the surfaces of this enclosure are modeled as 2D problems and then combined. This enables the shielding effectiveness of PCB enclosures or other electrical and electronic enclosures to be estimated.
Fault attacks constitute a threat against secure integrated circuits. If they can be conducted by different means, a large attention has recently been paid to the EM side-channel. EM fault attacks are performed through near-field probes. To be efficient, these probes must deliver an intense and localized field. Using 3-D electromagnetic simulations, this paper proposes guidelines for the design of...
The paper presents selected results of electromagnetic disturbance measurements recorded in working mine conditions. Attention has been brought to the most important phenomena which can be insufficiently reflected in the requirements of current EMC standards. The paper also refers to examples of potential lack of compatibility of mining equipment. The issues concern equipment produced by different...
