Abstract
To meet the requirements of electromagnetic (EM) theory and applied physics, this study presents an overview of the state-of-the-art research on obtaining the EM properties of media and points out potential solutions that can break through the bottlenecks of current methods. Firstly, based on the survey of three mainstream approaches for acquiring EM properties of media, we identify the difficulties when implementing them in realistic environments. With a focus on addressing these problems and challenges, we propose a novel paradigm for obtaining the EM properties of multi-type media in realistic environments. Particularly, within this paradigm, we describe the implementation approach of the key technology, namely “multipath extraction using heterogeneous wave propagation data in multi-spectrum cases”. Finally, the latest measurement and simulation results show that the EM properties of multi-type media in realistic environments can be precisely and efficiently acquired by the methodology proposed in this study.
