“…At the same time, the inequality (9) shows that as the length r of G(r) increases, b 2n (r) exhibits a much faster decay rate than b 2 (r), thereby leading to tighter bounds for P exc (r), or equivalently a higher level of confidence in the domain G(r). The Chebychev inequalities ensure that b 2n (r) is an upper bound for P exc (r), regardless of the distribution of γ, while it is impossible to ascertain whether P Gauss (r) is an upper or lower bound for P exc (r).…”

“…In the latter domain, statistical methods are commonly used to describe the field and power distributions in mode-stirred reverberation chambers [7,8]. Thin-wire setups, which are ubiquitous as interconnections in modern-day electronics, are also more and more prone to being analyzed stochastically [9,10]. We have successfully applied this modus operandi to thin-wire problems by evaluating the first four statistical moments of the observable with the aid of quadrature algorithms.…”

Abstract-Uncertainties in an electromagnetic observable, that arise from uncertainties in geometric and electromagnetic parameters of an interaction configuration, are here characterized by combining computable higher-order moments of the observable with higher-order Chebychev inequalities. This allows for the estimation of the range of the observable by rigorous confidence intervals. The estimated range is then combined with the maximum-entropy principle to arrive at an efficient and reliable estimation of the probability density function of the observable. The procedure is demonstrated for the case of the induced voltage of a thin-wire frame that has a random geometry, is connected to a random load, and is illuminated by a random incident field.

Abstract-A network analyzer with a bulk current injection (BCI) probe is proposed to measure the common-mode conversion coefficient for DC supply loops on a driver PCB of thin film transistor-liquid crystal display (TFT-LCD) panel. The proposed technique is used to predict the common-mode radiated emission caused by the DC supply loops, which highly correlates with the radiated emission measurements obtained for the TFT-LCD panel in a fully anechoic chamber (FAC). The proposed technique is also successful to estimate the reduction of a specific peak in the radiated emission spectrum by shielding the DC supply loops on a driver PCB of TFT-LCD panel. Electromagnetic simulation and equivalent-circuit modeling approaches are developed to confirm the common-mode radiation mechanism in this study.

Abstract-An effective fast equivalent cable bundle modeling method is proposed in this paper to study electromagnetic pulse response of complex cable bundle. Compared with traditional equivalent cable bundle method (ECBM), the complete cable bundle is equivalent to only one cable by modification of cable grouping method, which leads to reduction in number of cables and computation progress. The proposed method can perform well not only in pure resistance case, but also in frequency dependent load case by weighted average method (WAM). The computation time and memory acquirement for complete cable bundle model terminated in arbitrary loads have been further reduced by fast equivalent method compared to ECBM, and calculation precision is maintained to meet fast application need. Numerical simulation of coupled currents in observed cable located at a certain distance away from cable bundle by CST software is given to verify accuracy of the method under illumination of high altitude electromagnetic pulse (HEMP).
