NEMIG: 'The Challenges and opportunities for the characterisation and quantification of Stochastic Electromagnetic Fields' - Prof. Dave Thomas - 14th January 2016

Abstract: Near field measurement and modelling techniques for electronic equipment have been developed for many years. The complexity of modern electronics now requires a statistical approach. Efficient modelling tools for describing noisy electromagnetic fields in complex environments is paramount for tackling the development of the next generation of integrated circuits and chip architectures. C2C communication and wireless links between printed circuit boards operating as Multiple Input Multiple Output (MIMO) devices will become dominant features overcoming the information bottleneck due to wired connections. Designing the architecture of these wireless C2C networks will challenge standard engineering design tools. Device modelling and chip optimization procedures need to be fundamentally based on the underlying physics for determining the electromagnetic fields, the noise models and complex interference pattern. In addition, the input signals of modern communication systems are modulated, coded, noisy and eventually disturbed by other signals and thus extremely complex. To simulate the reaction of complex wireless C2C elements, new electromagnetic field simulation techniques are needed to describe a realistic system response for the development of future communication circuits, chips and systems.

This presentation will review recent advances both in electrical engineering and mathematical physics make it possible to deliver the breakthroughs necessary to enable this future emerging technology. Increasingly sophisticated physical models of wireless interconnects and associated signal processing strategies and new insight in wave modelling in complex environments based on dynamical systems theory and random matrix theory make it possible to envisage wireless communication on a chip level. This opens completely new pathways for chip design, for carrier frequency ranges as well as for energy efficiency and miniaturisation, which will shape the electronic consumer market in the 21st century and worldwide.
