Simulation of electromagnetic field exposure in resonant environments

无线通信是许多方案的关键，以减少运输对环境的影响，并提供未来城市环境（包括车辆乘客）所需的普及网络接入。因此，电磁安全是此类系统的设计、操作和公众接受度中的主要问题。欧盟最近公布了电磁场暴露的限制，但它们并不适用于车辆和建筑物等谐振环境。此外，在这些结构中出现的场分布是如此复杂，以致于通过测量来可靠地评估暴露是不切实际的。因此，这项建议涉及大规模模拟方法的开发和实验验证，以评估在这种环境中由于无线电传输而产生的场的特性。模型内容，分析方法，有效的模拟策略和现场缓解技术将得到解决，使用汽车和飞机为基础的案例研究。此应用程序是DTI技术计划提交的一部分。

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.
