“…There have been efforts to reconstruct the emission sources of near-field scanning with the differential evolution algorithm to ensure convergence to the optimal solution without the need for handling the ground plane separately [12], [13], [14]. Despite the difficulties in measuring near-field phases, especially at high frequencies, the differential evolution method can utilize amplitude-only near-field measurement [13], [14], [15].…”

“…For example, a wireless receiver may require that the background RFI levels are sufficiently low, typically -70 dBm or less, depending on the receiver's antenna and architecture, to ensure that the receiver can detect a minimum detectable signal (MDS) [12], [13], [14]. Hence, the RFI can be regarded as the primary concern when the received power from noise sources exceeds the MDS value [15]. Furthermore, characterizing the RFI makes it feasible to apply mitigation strategies to prevent associated potential problems, such as receiver front-end saturation [16], [17], [18], [19].…”

An inverse method of moments (MoM) approach is developed to estimate the equivalent electric/magnetic current sources to predict radio frequency interference (RFI) in electronic devices. The proposed method is designed to reconstruct the noise sources in electronic devices containing multiple radiating elements by using a finite metal object carrying electric surface currents. The surface current elements are further applied to calculate the electromagnetic fields on arbitrary observation planes near the device under test (DUT). The method is validated through numerical simulation examples, including electrictype CPU noise, magnetic-type non-planar HDMI connector noise, printed circuit board (PCB) with Wi-Fi and PIFA antennas, and heat sink embedded in the DUT. The results confirm less than 0.4 dB difference in the predicted pattern at the antenna operating frequency when a triangular segmentation is applied in the vicinity of the noise source area, and the equivalent surface current is calculated at the edges of the Rao-Wilton-Glisson (RWG) meshes. The proposed method is a promising 'source reconstruction' candidate for predicting the near-field radiation characteristics of electronic devices with multiple peaks and nulls in the near-field radiation pattern. The method helps estimate the level of RFI by summing up the contributions of all the dipoles of the equivalent noise source derived by solving forward and inverse problems. The RFI results based on the inverse MoM approach are validated by comparing them with those obtained from CST simulation, and good agreement is achieved between the two.

With the advancements in Industry 4.0 and the global demand for sustainable energy, power electronics devices are emerging as pivotal components for modern industrial, transportation, and energy delivery. Ensuring the security of these devices is of paramount importance for safeguarding the reliable operation of critical systems against any threats. In recent years, the issue of intentional electromagnetic interference (IEMI) attack and their related countermeasures have gained widespread attention in both military and civilian power electronics sectors. Here, a review of IEMI in power electronics is provided. Starting from the electromagnetic compatibility standards, the test setups for evaluating the device immunity are introduced. Due to different attack modes and propagation paths, IEMI illuminations are typically categorized into conduction and radiation, where their susceptibility studies, applications, and defence strategies are discussed, respectively. Finally, the existing challenges, ongoing trends, and future topics in this field are discussed.
