Simulation of electromagnetic field exposure in resonant environments

Abstract

Wireless communication is key to many schemes to reduce the environmental impact of transport and to provide the pervasive network access needed for future urban environments (including vehicle passengers). Thus, electromagnetic safety is a major issue in the design, operation and public acceptance of such systems. The EU has recently published limits for electromagnetic field exposure, but they do not readily apply to resonant environments such as vehicles and buildings. Also, the field distributions that arise in these structures are so complex that reliable assessment of the exposure by measurement is not practicable. This proposal therefore concerns the development and experimental validation of large-scale simulation methods to assess the characteristics of fields due to radio transmissions in such environments. Model content, analysis methods, efficient simulation strategies and field mitigation techniques will be addressed, using car and aircraft based case studies. This application is part of a DTI Technology Programme submission.
