“…Due to the complexity of modern electronic systems, this problem has been studied at various subsystem levels ranging from components [9,[12][13][14] and printed circuit boards (PCB) [15][16][17][18][19][20] to cables [21][22][23][24][25][26][27] and enclosures [15,[25][26][27][28][29][30], with some groups even consider-ing the system as a whole [31]. Furthermore, this problem is typically separated into four areas of study: coupling, energy distribution, device response, and system response.…”

Because modern electronic systems are likely to be exposed to high intensity radiated fields (HIRF) environments, there is growing interest in understanding how electronic systems are affected by such environments. Backdoor coupling in particular is an area of concern for all electronics, but there is limited understanding about the mechanisms behind backdoor coupling. In this work, we present a study on printed circuit board (PCB) backdoor coupling and the effects of via fencing. Existing work focuses on ideal stackups and indicates that edge radiation is significantly reduced by via fencing. In this study, both full wave electromagnetic modeling and experimental verification are used to investigate both ideal and practical PCB stackups. In the ideal scenario, we find that via fencing substantially reduces coupling, which is consistent with prior work on emissions. In the practical scenario, we incorporate component footprints and traces which naturally introduce openings in the top ground plane. Both simulation and experimental data indicate that via fencing in the practical scenario does not substantially mitigate coupling, suggesting that PCB edge coupling is not the dominant coupling mechanism, even at varying angles of incidence and polarization.

“…Veropoulos and Papakanellos [8] study twisted-wire pairs excited by random plane-wave fields. The same authors derive a closed-form expression for the probability density function of the induced far-end voltage of a PCB trace in certain cases of field descriptions [9]. In their study, the field amplitude and only one of the three angles, which are polarization angle, elevation angle of incidence, and azimuth angle of incidence, are random at the same time, while the other parameters of the field are fixed.…”

Stochastic electromagnetic fields coupling to printed circuit board (PCB) traces are important to the understanding of electromagnetic compatibility at high frequencies when the circuits or systems are electrically large. In this article, it is studied both numerically and analytically, and the factors affecting the absorbed power are investigated. We present new methods to determine the level of coupling on PCB traces or other transmission lines on a dielectric substrate. A Monte Carlo method is applied to generate random uniform fields, and the quasi-TEM transmission line model is employed to compute the response of the trace for each plane wave numerically. In the analytical method, the closed-form expressions of the zero-order and the first-order approximations are established for the PCB trace. Based on the first-order approximation method and the numerical results, a computationally efficient empirical method is developed to estimate the power received. The absorbed power increases with frequency in the electrically short case after which multiple resonances can be seen. The absorbed power in the matched case is neither the largest nor the smallest among all the cases. It increases with the square of the substrate height but decreases with the permittivity of the substrate.Index Terms-Absorption cross section (ACS), printed circuit board (PCB) trace, stochastic electromagnetic fields, transmissionline coupling.

“…In [2], numerical methods, such as method of moments (MoM), finite-difference time-domain (FDTD) method, finite-element method (FEM), transmission-line matrix (TLM) method are studied for EMC problems in passive structures. Also, many researchers have focused on developing numerical methods to treat the transmission lines or interconnects of electronic gadgets exposed to an external EMI coupling [3][4][5][6][7].…”

This study proposes a new approach to hybrid a circuit and field analysis in order to evaluate the susceptibility of a low-noise amplifier against electromagnetic interference. The proposed method employs an equivalent circuit model for active elements and a full-wave time-domain analysis for the passive parts. To this end, two methods, finite integrated technique and the method of moments, are combined through an innovative algorithm. The output of the suggested hybrid technique is an equivalent circuit model which predicts well the susceptibility of the illuminated low noise amplifier. To validate the model, measurements are performed in an anechoic chamber. The authors will show that the proposed method provides a satisfactory accuracy.
