Grant Description

Summary and Description of the grant

Electromagnetic modelling is an essential tool for electromagnetic compatibility characterisation of electrical equipment. All electrical equipment must satisfy international standards for electromagnetic compatibility (EMC) to ensure that it does not interfere with other equipment or is susceptible to external interference. The use of simulation software greatly reduces the design and development of new equipment that confirms compliance to EMC standards, so it is widely used throughout the electrical industry. The increasing processor clock signal speeds and the decreasing size of electronic devices has made electromagnetic simulation very demanding. It is not possible to fully model the complexity of electronic devices with full 3D electromagnetic simulators. Some form of simplification of the electronic devices is required. A recent EPSRC funded project by the George Green Institute for Electromagnetics Research has developed a way of characterising the electromagnetic emissions from printed circuit boards (PCBs) using near field scan data so that a simplified model of their behaviour can be constructed. The produced models have been demonstrated to be suitable for use in electromagnetic simulators. This work was very successful and achieved all the project objectives, but was only demonstrated on simple PCB structures and in the frequency domain. For this method to be fully incorporated in the industrial sector, however, it needs to encompass all common PCB structures, their interconnects and be extended into a time domain approach. This proposal will research extending the techniques developed so far using near field scans of PCBs so that it can provide simplified models of all common types of PCBs and include their interconnects and a way of combining their characteristics into complete system models. The work will also look at ways of extending the method into the time domain. In this was it is hoped that models suitable for use in full 3D electromagnetic simulators can be developed to enable engineers to provide EMC characterisation at the design stage.
