A Hybrid Approach for Assessments of Equivalent Emission Sources and Electromagnetic Environments

Abstract This paper presents a method for equivalent emission source determination by application of LLAs (Large Loop Antennas). A review of different types of LLAs is carried out and their characteristics regarding emission source evaluation are emphasized. A hybrid technic is applied for obtaining the electric fields based on previous measurement of magnetic fields combined with an analytical and numerical approach. This methodology is proposed as an alternative to face the constraints concerning to the near electric fields measurements and calculations.摘要 本文提出了一种借助大型环天线（Large Loop Antennas，LLAs）确定等效辐射源的方法。文中对不同类型的大型环天线进行了综述，并着重阐述了其在辐射源评估方面的相关特性。研究采用混合技术，结合前期磁场测量结果与解析及数值方法来获取电场。针对近场电场测量与计算面临的诸多限制，本研究提出的该方法可作为一种替代解决方案。
