The paper deals with the shielding enclosure design using evolutionary algorithms without predetermined conditions. The designed shield consists of an array of elements that rep-resent conductive or non-conductive parts. The expected output is to design a shield with sufficient balance between shielding effectiveness and transparency in systems that need an optical line of sight. The wide frequency transparent shielding design is a complex task that researchers so far mostly solved by composite polymers. The authors use a different approach using traditional conductive material and element folding technology. Element assembly is performed by an evolutionary algorithm that decides the properties of the material used and creates the optimal structure to achieve the desired results. The paper describes the design concept for planar shielding with metaheuristics and the preliminary results.

The radio frequency (RF) coupling to electronic devices impacts their EMC performance. The functionalities of a working electronic device may be disrupted when the electromagnetic (EM) coupling reaches a certain level. Studies of the EM coupling to printed circuit boards (PCBs) are therefore essential for RF susceptibility and EMC purposes. For decades, researchers focused on the analytical modeling of EM coupling to transmission lines. However, when it comes to more realistic PCBs the analysis usually still relies heavily on full-wave simulations because of the complexity of the structures and the lack of analytical solutions. Using a traditional full-wave modeling approach, however, could take hours to investigate the EM coupling from the external plane wave to the structure for one incident angle of arrival and polarization. In this paper, we present a methodology using reciprocity that allows for rapid estimation of the voltage induced in the terminations for multiple incident angles of the incoming plane wave and load values based on just one full-wave simulation. This reciprocity-based method is combined with a segmentation technique to enable the capability of studying the coupling to more realistic PCBs. For the cases studied here, estimates could be found in minutes using this approach rather than hours using a full-wave simulation. Estimates were within 2–3 dB of estimates using full-wave simulations for a simple trace structure. Accuracy was not as good for individual angles of arrival of an incident RF wave to a complicated structure including two integrated circuit (IC) packages connected by a trace, but statistical estimates of coupling were within 2–3 dB.

For mobile DRAM, low EMI (Electro-Magnetic Interference) chip architecture is highly required. So, mobile DRAM's EMI characteristic using center-placed pads and edge-placed pads has been investigated. Our near-field scan measurement results show that the peak H-field magnitude of LPDDR5 using edge-placed pads is lower by 11.5 dB than that of the other one using center-placed pads. Furthermore, when comparing our measurement results to our simulation results showing that the power plane resonance of PoP (Package-on-Package) affects low frequency EMI radiation significantly, we have also noticed reasonable agreement on the peak H-field magnitude trend.

The problem considered in the work is related to ensuring the electromagnetic compatibility of track circuits with a parallel traction network. To evaluate the influence of interference from the alternating current traction network on the operation of the track circuits a simplified model has been developed. The model is based on the well-known multiconductor transmission line method, however, its use for modeling a traction network is difficult due to the longitudinal structural inhomogeneity of the traction system. The simplification proposed in the work assumes that the track circuit equipment connected to the rails insignificantly influence on the distribution of currents in traction network conductors. These assumptions make it possible to neglect the equipment of track circuits at the first stage of modeling, which greatly simplifies the equivalent circuit of the traction network, and allows us to represent it in the form of several homogeneous sections of multiconductor transmission lines with rolling stock units between them. Simulation of induced alternating current interference in the rails of the track with direct current traction is carried out at the second stage, taking into account the design features and electrical parameters of track circuits, as well as specific values of rail-to-ground conductance and earth conductivity, using the values of the currents in the traction network conductors determined in the first stage.

Wireless earbud is the most sold wearable type in the consumer electronics market. As wireless earbuds offer more functionalities, the increased complexity and integration may introduce undesirable coupling between different components. One of the undesirable coupling is the magnetic coupling between the earbud main logic board (MLB) and the speaker coil. The low frequency current ripples on the MLB power rail may induce current with acoustic frequency components on the speak coil and lead to unpleasant audible noise. In this paper, the magnetic field generated by an earbud MLB is investigated through simulation with 3D FEM solvers and measurement with a low frequency H-field probe.

Common-mode choke coil (CMC) is used in vehicles and electronic devices to improve electromagnetic compatibility (EMC), and the analysis of the CMC effect is essential to improve the design quality of EMC. In this paper, the suppression effect of CMC for the common-mode (CM) signal converted from the differential-mode (DM) signal is analyzed using a chain-parameter matrix. The chain-parameter matrix of the CMC was obtained from the SPICE model and the measured data. And then, the amount of conversion level from DM signal to CM signal was calculated using the chain-parameter matrix of the signal source, the termination, the cable, and the CMC. The CM signal level was calculated for the shielded twisted pair cable with one pair considering imbalances of the signal source, the termination, the cable, and the CMC. The calculation value was compared to the measurement value due to confirm the validity of the method, and the calculated results were in close agreement with the measurement value. The investigation results showed that we should pay attention to the CMC imbalance when the cable is well balanced. In addition, the results suggested that the CMC should be prepared at both ends of the cable to reduce the current outside the shield.

Tissue-reduced virtual family models are developed for the RF-induced heating assessment of passive implantable medical devices. The models are developed based on the Gaussian mixture model. The RF-induced heating of four representative passive device systems is evaluated inside the original human models, tissue-reduced human models, and the ASTM phantom at three landmark positions under a 1.5 T MRI system. From the results of these simulations, it is observed that the RF-induced heating from the tissue-reduced virtual family models is highly correlated to that obtained from the original human body models. It demonstrates the feasibility of using tissue-reduced models for the RF-induced heating testing of implantable medical devices.

I/O pin counts have been able to increase significantly thanks to ball grid array (BGA) packages. This I/O pin counts increase brings challenges to break out signals and ensure sufficient shielding effectiveness (SE). Shielding can is often used to enhance the SE of the package but in many devices, conformal sputtering shielding is a better option. This paper presents a method to improve the SE by adding a VSS ground ring structure to the sputtering coat. The simulated results show the proposed structure provides 20 dB more SE compare to the structure without a VSS ground ring.

Due to the on-going changes in modern technologies, deeper investigation of the complex automotive electromagnetic environments is necessary. Since conventional standardized testing methods are lacking characteristics met in real automotive electromagnetic environments, a risk-based electromagnetic compatibility approach can conclude to detection of potential electromagnetic interference threats. A measurement of a real automotive electromagnetic environment is proposed and investigated using two different measurement methods addressing the temporal and spatial variations of the electromagnetic environment. This investigation reveals the complexity of real electromagnetic environments and the difficulty of them being sufficiently described to warrant electromagnetic compatibility due to continuously varying parameters over space, time, and frequency. The random-walk technique is applied and compared with a discrete static measuring technique of acquiring data. Examination of the collected data is made along with discussion on their possible application through statistical tools.
