“…We found that the addition of fringing capacitances at the edges was not necessary for the models tested. Stamping all the elements into the MNA matrix results in (9). This allows the computation of all the desired quantities like the impedances of interest.…”

“…There are several different formulations used for modeling the plane-pairs. Some are based on analytical formulations like [5], [6], finite difference time domain (FDTD) models like [7], transmission line modeling (TLM) approach like [8], [9], etc. The first partial element equivalent circuit (PEEC) [10] based approach in plane-pair modeling was presented in [11].…”

In this paper, we present an improved plane-pair model for power distribution system modeling using the partial element equivalent circuit approach. The modified nodal analysis with a sub-meshing strategy leads to an efficient and accurate circuit solution in both the frequency domain and time domain.Index Terms-power distribution networks, power integrity analysis, simulation algorithms 159 978-1-4799-3643-4/14/$31.00 ©2014 IEEE

“…Powerful ultra-wideband (UWB) pulses of the nanosecond and sub-nanosecond ranges can penetrate and damage various radioelectronic devices (REDs). Engineers consider conducted interference, induced interference in a system, and radiated interference between systems [1]. To ensure electromagnetic compatibility (EMC) of electronic systems, an electromagnetic interference must be controlled and limited.…”

<p>This paper presents a novel technique for improving the performance of a modal filter by using an electromagnetic absorber. The study considers a two-conductor modal filter based on a microstrip transmission line. The authors analyzed the effect of the absorber on the MF performance in suppressing conducted and radiated interferences (in the near and far fields). The frequency characteristics of the device were then redefined into the time characteristics in the Advanced Design System. As an excitation, the authors used an ultra-wideband interference pulse of 155 ps (at 0.5 level) and then employed N-norms to estimate and characterize the decomposed pulses. The results show that the use of the absorber can significantly improve the attenuation of the ultra-wideband interference. It was experimentally demonstrated that the value of N1 decreased by a factor of 4.31, N2 – by a factor of 6.52, N5 – by a factor of 1.87. In terms of radiated interference in the near field, the improvement in attenuation of each norm achieved at least 2.81 times. The analysis of the characteristics in the far field showed that the use of the electromagnetic absorber allows reducing the transmission coefficient on average by 2.25 times at a distance of 1 m. To validate the measurement results, the electrodynamic simulation of the modal filter characteristics in the frequency range up to 6 GHz was carried out and showed full agreement with the experimental results.</p>
