| Outline of Final Research Achievements |
A novel measurement technique was developed for Poynting vector (electromagnetic energy flow) distributions of radio waves emitted from electronic devices at GHz frequencies. A two-dimensional array of electromagnetic vector sensors was formed on a metasurface structure, and a measurement and visualization system for Poynting vector distributions was constructed. Based on a detailed analysis of Poynting vector behaviors around a radio wave source, propagation and coupling of electromagnetic energy between the source and the sensors were investigated.

| Academic Significance and Societal Importance of the Research Achievements |
今回開発した電磁界ベクトルセンサを用いると、電磁波ノイズエネルギーの発生・伝搬及び他機器への結合を包括的に計測・評価できるようになり、環境電磁工学やアンテナ・伝搬分野における学術的意義は大きい。またこれは従来にない電磁環境計測手法であり、今後無線通信を利用するIoT機器が急増する社会において、電子機器における電磁波ノイズ発生源の探査や、ノイズが他機器へどのように伝搬し影響を与えるか等の実測評価にきわめて有用である。
