EMC Simulation and Modeling

Measurements and modeling of EMC applied to cabling and wiring

A myriad of cables transport power and communication signals in larger buildings and installations. Cross talk between cables and connected equipment is a major concern. Regulations do exist, but often show to be insufficient to avoid undesirable coupling. The present thesis research addresses this problem and provides a tested model for the interference coupling in buildings, in particular tho...

EMC Simulation in the Design Flow of Modern Electronics

source file. This near-field source is then imported into a second simulation of the anechoic chamber, using a much coarser mesh. According to Huygens’ Principle, the second simulation will create the same radiated emissions as the full 3D model, and it only requires a few minutes. The same approach can be used for modeling other structures which can affect emissions, such as the housing of a PCB.

EMC’04/Sendai LIGHTNING STEPPED LEADER NUMERICAL SIMULATION

A lightning stepped leader model is developed. To predict the stepped leader is important to protect installations at ground against lightning. The numerical technique TLM (Transmission-line matrix) is applied.

EMC’04/Sendai Control of Unintentional Electromagnetic Waves from Digital Circuits: Efficient EMC Modeling of Devices and PCBs

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...
