This paper presents the electromagnetic interference and electromagnetic susceptibility characteristics of the railway telecommunication intra-subsystem. These are for assessing the electromagnetic compatibility inside the railway telecommunication subsystem and providing input data for electromagnetic compatibility analysis of other subsystems (intra-system analysis). This paper shows the opti...

A research project has been carried out for the last five years, the subject of which is to develop effective methods to control electromagnetic noise radiation from digital electronic devices. Engineering approaches were chosen and some new modeling methods of electromagnetic phenomena around a printed circuit board are shortly described in relation to EMI subjects. Those results have been com...

When computing an electromagnet ic field using the f ini te element method it is possible that, although Maxwell’s equations are discret ized accurately, highly inaccurate computational results are obtained. In those cases it can easily be s h o w n that (some of) the electromagnetic compatibi l i ty relations (field properties that follow from Maxwell’s equat ions) are not satisfied. The diver...

In this paper, a data-driven method to precisely simulate the detector response of anti-neutron depositing in Electromagnetic Calorimeter (EMC)at BESIII is introduced. A large data sample can be selected using decay $J/\psi\to p\bar{n}\pi^{-}$ from 10 billion $J/\psi$ events. The detection efficiency for and various observables anti-neutrons interacting EMC are simulated, taking correlations am...

Nonlinear interference and distortions have a profound impact on wireless communication system operation, especially under conditions of severe electromagnetic environment (overcrowded spectrum, strong interfering signals, multipath and multi-signal environment etc.). In this paper, we propose a new behavioral-level simulation technique – the "instantaneous" quadrature technique, which can be e...

Due to their size and complex geometry, large heatsinks such as those used in the power electronics industry may enhance the radiated emissions produced by the circuits employing them. Such enhancement of the radio frequency (rf) radiation could cause the equipment to malfunction or to contravene current EMC regulations. In this paper, the electromagnetic resonant effects of heatsinks are exami...
