Thermal radiation is an electromagnetic wave originated from thermal vibration of charged particles in a material. It is industrially or naturally easily obtainable energy. However, it is dispersed over a wide spectral region covering the Planckian distribution on its own, and it is also weak directional indistinct radiation. Therefore, it is not often effective to concentrate its energy on a specified wavelength (band or region) and bring out engineering functions as in the case of laser beam.The present study aims to develop new techniques for controlling and converting the thermal radiation into spectral functional radiation which emphasizes an specified wavelength band. In the present study, on the basis of electromagnetic wave theory, spectroscopy, solid state physics and heat transfer science and engineering, we make experimental and theoretical studies of spectroscopic thermal engineering in order to realize hardware systems which is effective for energy engineering and life env … More ironmental engineering.Specifically, in the term of the three years (2005-2007), Makino, Wakabayashi and Matsumoto (Kyoto University) considered (1) interference of spherical wave of thermal radiation emitted by a film system and (2) a theoretical model in which an electromagnetic wave theory for a spherical wave is combined with Planck's theory of thermal radiation, and (3) fabricated film system type emitters. (4) They developed a new excellent wide-spectral-range high-speed spectrophotometer system for simultaneous measurement of spectra of specular reflectance, hemispherical reflectance and directional emittance of surfaces, and (5) they experimentally verified Kirchhoffs law on thermal radiation at an electromagnetic wave level. In addition, Makino actively made several plenary, keynote and review speeches in several domestic symposiums and international conferences on thermal engineering from the viewpoint of his supervisor position of the present study. Yoshida (Kyoto University) thermal-systematically considered thermovoltaic and thermophotovoltaic generation systems by using the spectral functional radiation. Hanamura (Tokyo Institute of Technology) (1) made spectroscopic experiments and calculations on spectral control' of emittance of rectangular microstructure cavities, (2) designed an experimental apparatus of nanogap generation by using evanescent wave, and (3) tried to actually fabricate GaSb photovoltaic cells in his laboratory. Yamada (Shibaura Institute of Technology) made spectroscopic experiments and calculations (1) on radiation emitted by the film type emitter and (2) on reflection of radiation of human skins. (3) He also tried to improve power conversion efficiency of a dye-sensitized solar cell. Less

热辐射是电磁波，源自材料中带电颗粒的热振动。它在工业上或自然而然地获得能量。但是，它被分散在覆盖普兰克分布的广泛频谱区域，也是弱的定向辐射。因此，将其能量集中在指定的波长（带或区域）上并像激光束一样发挥工程功能并不是有效的。目前的研究旨在开发新技术来控制和将热辐射转化为光谱功能辐射，从而强调指定的波长带。在本研究中，基于电磁波理论，光谱，固态物理和传热科学和工程，我们对光谱热工程进行实验和理论研究，以实现能够有效的硬件系统，这些系统对能源工程和生活env有效…更具熨斗工程，特别是在三年的时间里（20055-2007-2007-2007-2007）大学）考虑（1）通过膜系统发出的热辐射的球形波和（2）理论模型，其中球形波的电磁波理论与普朗克的热辐射理论结合在一起，以及（3）制造的膜系统类型发射器。 （4）他们开发了一种新的出色的广谱高速分光光度计系统，用于简单测量光谱反射率，半球反射和表面的方向发射的光谱，以及（5）它们在电子电磁波水平上在热辐射方面实验验证的Kirchhoff法律。此外，Makino从本研究的主管职位的角度从几个国内研讨会和国际热工程会议上进行了几次全体会议，主题演讲和评论。吉田（京都大学）通过使用光谱功能辐射，在系统系统上被视为热伏型和热伏燃料生成系统。 Hanamura（东京技术研究所）（1）对矩形微观结构城市排放的光谱控制进行了光谱实验和计算，（2）设计了通过使用EvineScent Wave生成纳米op的实验设备，并且（3）试图在他的实验室中制造Gasb Photovoltaic细胞。 Yamada（Shibaura技术研究所）对膜类型发射器发射的辐射和（2）对人体皮肤辐射的反射进行了光谱实验和计算（1）。 （3）他还试图提高对染料敏感的太阳能电池的功率转换效率。较少的
