ASpectroscopic Tharnal Eoginming Approach to Development of New Control Techniques of Spectrally Functional Thermal Radiation

热辐射是由带电粒子在材料中的热振动产生的电磁波。它是工业上或自然上很容易获得的能源。然而，它本身分散在一个覆盖普朗克分布的宽光谱区域，而且它也是弱定向模糊辐射。因此，将能量集中在特定的波长(波段或区域)并发挥工程功能通常不是有效的，本研究旨在开发新的技术来控制热辐射并将其转换为强调特定波长波段的光谱功能辐射。本文以电磁波理论、光谱学、固体物理学和传热学与工程为基础，对光谱热工程进行了实验和理论研究，以期实现适用于能源工程和生活环境…的硬件系统。具体地说，Makino、Wakabayashi和MatSumoto(京都大学)在2005-2007年的三年时间里考虑了(1)薄膜系统发出的热辐射的球面波的干涉，(2)将球面波的电磁波理论与普朗克的热辐射理论相结合的理论模型，以及(3)制造薄膜系统类型的发射器。(4)研制了一套性能优良的宽光谱范围的高速分光光度系统，用于同时测量表面的镜面反射比、半球反射比和定向发射率光谱；(5)在电磁波水平上实验验证了基尔霍夫热辐射定律。此外，Makino还从本研究的指导地位出发，在国内多个热工研讨会和国际会议上积极发表了几次全体会议、主题演讲和回顾演讲。吉田(京都大学)利用光谱功能辐射对热伏和热光伏发电系统进行了热系统研究。花村(东京工业大学)(1)对矩形微结构腔发射度的光谱控制进行了实验和计算，(2)设计了利用逝去波产生纳米间隙的实验装置，(3)在他的实验室尝试实际制造GaSb光伏电池。山田(柴浦理工学院)进行了光谱实验和计算(1)薄膜发射器发射的辐射和(2)人体皮肤辐射的反射。(3)他还试图提高染料敏化太阳能电池的功率转换效率。较少

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
