| Outline of Final Research Achievements |
We studied generation of high power electromagnetic microwave by a compact pulse power generator. As a result, it was found that the shorter the rising time (<10nsec) of the applied pulse voltage, the larger the electromagnetic wave output. The generation of electromagnetic waves was less than 100 nsec after the pulse voltage was applied. From these results, it is considered that a pulse generator with a pulse rise time less than several nanoseconds, a pulse width less than 100 nsec, and a high frequency repeatedly is required in order to efficiently generate electromagnetic waves by spark gap discharge.

| Academic Significance and Societal Importance of the Research Achievements |
高電圧パルス放電で発生する超広帯域電磁波は、通常の半導体で発生する電磁波よりも出力が大きい。このため、無線通信、高分解能レーダー、生体の活性化など様々な応用が考えられる。よって、本研究では、高電圧パルス放電で高出力の電磁波を発生させる条件について研究を行った。その結果、高電圧パルス放電を用いた電磁波の発生では、立ち上がり時間の短いパルス電圧が必要であることがわかった。また、電磁波の発生時間はパルス電圧印加後の約数十ナノ秒以下のごく短時間であることもわかった。
