Recently, the electromagnetic radiation to the living body is paid to attention as a problem of damage to the living body mechanism. Moreover, the GHz band comes to be used to communicate, so the influence on the living body of this band is paid to attention. This research measures the reflection of the millimeterwave and the submillimeter wave as a basic rematch on irradiation of the millimeter wave and the submillimeter wave into living body. Our research of the past started from heat degeneration to living body using the gyrotron, and at the millimeter wave band, the living body sample was heat degenerated by about 300 mW rises oscillator. Lb apply these researches to clinical, the reflection of the millimeter wave from living body samples was measured And, they were examined in detail The permittivity changes into the living body sample by changing of variations in temperature and the protein structure. We measured the reflected wave with the detection In addition, the measurement … More of the reflection was enabled at the same time as irradiating it. Moreover, the absorption of the electromagnetic radiation to the sample was observed by measuring the reflected wave under the irradiation. The output was controlled with an attenuator, and the time to the heat degeneration and the correlation with the output were obtained. It is effective to observe Anti-Reflecting effect with the thin Era dielectric substance, and to improve the absorption efficiency of the electromagnetic radiation of the sample. As a result, suppressing extra irradiations other than a target part when irradiating it became possible. Moreover when transmitting, the development of a flexible wave guide was tried. The wave guide was made for trial purposes by using teflon with low dielectric dissipation factor They obtained high transmission efficiency In addition, it has been obtained that the influence on the winding is a little. The cooperation of Fukui University was received based on these results and the irradiation equipment by the high power electromagnetic radiation using gyrotron was developed. As a result, even if various applications were used, an irradiation output enough for the degeneration of the living body could be obtained. The irradiation efficiency improvement by the AR effect and the utility of a flexible waveguide were confirmed here. Less

最近，对生命体的电子辐射被引起人们的注意，这是对生命身体机制损害的问题。此外，GHZ乐队开始用于交流，因此对该乐队的活体的影响引起了人们的关注。这项研究衡量了毫米波和亚毫米波的反射，作为毫米辐射的基本复制，并将其毫米波和亚毫升波向生物体内进行。我们对过去的研究始于使用陀螺仪的热变性到活体，在毫米波带上，活体样品被约300兆瓦的振动器升温。 LB将这些研究应用于临床，测量了活体样品中毫米波的反射，并通过改变温度和蛋白质结构的变化来详细检查它们对活体样品的介电常数变化。除了检测外，我们测量了反射波的测量……更多的反射是在与照射的同时启用的。此外，通过测量辐照下的反射波观察到电子辐射对样品的抽象。输出通过衰减器控制，并获得热变性的时间以及与输出的相关性。观察到薄时代的饮食物质，并提高样品电子辐射的抽象效率，这是有效的。结果，在辐照时抑制除目标部分以外的其他辐射变得可能是可能的。此外，在传输时，尝试了柔性波导指南的开发。通过使用低饮食耗散因子的特氟龙来制作波浪指南，它们还获得了很高的传输效率，因此已经获得了对绕组的影响有些略有。基于这些结果，收到了福克大学的合作，并开发了使用Gyrotron的高功率电子辐射的辐射设备。结果，即使使用了各种应用，也可以获得足够的辐射输出，以使活体的退化。这里确认了通过AR效应和柔性波导的效率提高的辐照效率。较少的
