项目摘要

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

热辐射是源自材料中带电粒子的热振动的电磁波，它是工业上或自然容易获得的能量，但它本身分散在覆盖普朗克分布的宽光谱区域，并且它也是弱方向性的。因此，像激光束那样将其能量集中在特定波长（波段或区域）并发挥工程功能通常并不有效。本研究旨在开发控制和转换热能的新技术。本研究以电磁波理论、光谱学、固体物理和传热科学与工程为基础，对光谱热工程进行实验和理论研究。实现对能源工程和生活环境工程有效的硬件系统。具体来说，在三年（2005-2007）期间，牧野、若林和松本（京都）大学）考虑了（1）薄膜系统发射的热辐射球面波的干涉，以及（2）球面波电磁波理论与普朗克热辐射理论相结合的理论模型，以及（3）制造的薄膜(4)他们开发了一种新型优良的宽光谱范围高速分光光度计系统，用于同时测量表面的镜面反射率、半球反射率和定向发射率。 (5)在电磁波水平上实验验证了基尔霍夫热辐射定律。此外，牧野以现任导师的身份，积极在国内多个热能工程研讨会和国际会议上作了多次全体会议、主题报告和综述演讲。吉田（京都大学）利用光谱功能辐射系统地考虑了热伏打和热光伏发电系统。（1）对矩形微结构腔的发射率进行光谱实验和计算，（2）设计了利用倏逝波产生纳米间隙的实验装置，（3）在他的实验室中尝试实际制造GaSb光伏电池。（芝浦工业大学）对（1）薄膜型发射器发出的辐射和（2）人体皮肤的辐射反射进行了光谱实验和计算。 (3)他还尝试提高染料敏化太阳能电池的电能转换效率。
