The study of the generating and affecting of the high electric field by the radiating of the electromagnetic wave for the cancer treatment method using the ultrashort pulsed high electric field

本研究设计了一种紧凑型高功率脉冲电磁波发生器，利用纳秒脉冲功率发生器产生高强度电场用于癌症治疗。在L-C逆变电路中采用了SF6气隙开关和脉冲压缩电路，以获得具有高频元件的脉冲高压。通过脉冲电磁波发生器能够在焦点处产生对于癌症治疗有效的50 kV/cm的峰值电场强度。这是世界上第一例用光学方法测量电磁波的电场。与直接施加电场一样，电磁波可以治疗癌症，因为电磁波的电场影响细胞。

This work focuses on the design of a compact high power pulsed electromagnetic wave generator using a nanosecond pulsed power generator to apply a high-intensity electric field for a cancer treatment. A SF6 gas gap switch and pulse compression circuit were used in the L-C inversion circuit to obtain a pulsed high voltage with a high frequency element. The peak electric field intensity of 50 kV/cm that is effective for the cancer treatment has been able to be generated at the focal point by the pulsed electromagnetic wave generator. This is the first case in the world that the electric field of the electromagnetic wave was measured by an optical method. As with the directly applying of the electric field, the electromagnetic wave can treat the cancer because the electric field of the electromagnetic wave affected the cells.
