Commercial of the shelf (COTS) SRAMS were investigated by measurements and simulation in terms of radiation hardness. For the simulations the GEANT4 tool was used. With GEANT4 it is possible to determine the different particles generated by the applied energy as well as the radiation source. It was found that the single event upsets (SEU) is related to the(More)
{ The knowledge of the current distribution on the ground plane of a Printed Circuit Board (PCB) is important to overcome many electromagnetic compatibility (EMC) problems. In this paper a Method of Moments (MoM) algorithm is used to evaluate the surface current distribution on the ground plane. To consider the eeects of GND/VCC-planes to the signal(More)
The purpose of this work is to develop a knowledge base which allows for the assessment of the influence of individual construction parameters on a mode stirred chamber's performance in its particular area of application. With this knowledge, it would be possible to adapt a chamber for a particular purpose, e.g. to use the chamber for electromagnetic(More)
Due to the high frequencies of analog and/or digital signals and a high package density on Printed Circuit Boards (PCB), problems occur concerning re-ection, crosstalk, radiation, and irradiation. New design methods have to consider the analysis of the expected radiation behaviour already during the design{phases of a PCB. If violations of the legal(More)
February 1997, Zurich, Switzerland, pages 241 247 A HYBRID METHOD BASED ON THE MULTICONDUCTOR TRANSMISSION LINE EQUATION AND THE METHOD OF MOMENTS F. Sabath , H. Garbe University of Paderborn C-LAB/ASE Paderborn Germany University of Hannover Hannover Germany Abstract: A hybrid method which combines the Method of Moments (MoM) and the multiconductor(More)
Common mode radiation often is the predominant contribution to the overall radiation from printed circuit boards. Since the return paths for common{mode currents are via displacement current, the proximity of the printed transmission lines to nearby metal objects become important. It is shown that common mode currents are due to the asymmetry of the printed(More)
This paper focuses on the coupling of ultra wideband (UWB) fields into marine equipment and discusses possible hardening techniques to increase the equipment's immunity. An evaluation procedure to determine the coupled disturbances e.g. the induced voltage at the input of an electronic component using numerically computed field and coupling transfer(More)
The last two decades have witnessed increased interest in High-Power Electromagnetics (HPEM), particularly generation of high-power electromagnetic fields and their effects on electronics. Up to now most investigations on HPEM are characterizing the HPEM environment (e.g. source output, HPEM threat) employing frequency domain parameters of classical EMC.(More)
