“…This problem is relevant for the analysis of the electromagnetic interference signals induced in cables that connect devices such as control computers and actuators, e.g., in buildings, in automobiles or in aircrafts [16]. In many cases of practical interest, these interconnecting cables are hidden from view being either buried or embedded inside walls of buildings or in the fuselage of an aircraft.…”

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.

“…At first, it was used as a system design methodology for formalizing the design of electrical systems to withstand the effects of various EM threats [4]. Afterwards, with the efforts of many researchers [5][6][7], it became a simulation tool for the prediction of EM interferences generated by external EM threats on systems [8][9][10][11][12]. In the EMT method, electronic systems can be decomposed into manageable sizes of subvolumes which can be modeled by different methods, numerically or experimentally.…”

Abstract-Simulations based on electromagnetic topology (EMT) have been carried out to analyze an external electromagnetic pulse interaction with a shielded coaxial cable linking two systems together. The proposed EMT approach, combined with the SPICE model of the shielded cable, can be applied in the transient simulation directly and used for the electromagnetic interference analysis of systems including nonlinear devices. The effects of the outer terminators, cable length, and connection of the voltage limiter on the induced voltages at the systems are studied by using the proposed EMT approach. It has been found that adding a resistance between the system's shielding enclosure and the ground can effectively reduce the coupling through the shielded cable. The cable length affects the pulse-widths rather than the magnitudes of the induced voltages. The results also show that the voltage limiter can reduce the induced voltages but at the same time result in mismatch at the source or load.

Abstract-Transient electromagnetic topology (TEMT) method is presented briefly first and then three typical configurations, namely, a transmission line network, a wire penetrating a cavity aperture and then connecting to a device, and two systems connected by a shielded cable radiated by an electromagnetic pulse, are analyzed by using the TEMT method. The currents induced at the loads obtained by the TEMT method are compared with those from the experiment. The good agreement of the numerical results with the experimental ones validates the TEMT method.
