The purpose of this study is to examine the possibility for creating an optically functional surface by constructing nano-structure on a solid surface. In the first year of this study, a numerical method for predicting radiative characteristics of a surface with nano-structure has been developed. This numerical method is a finite element method (FEM) for solving the Maxwell Equations and gives a 2-dimensional scattering electric field of radiation scattered by an object with nano-structure surface. This numerical code is applicable for surfaces with several nano-structure. The applicability of the numerical method for predicting radiative characteristics of a surface with nano-structure has been demonstrated. This study was entitled "Numerical Investigation for Radiative Characteristics of a scale of Morpho butterfly" and published in "Thermal Science and Engineering."In the second year, we predicted a nano-structure of surface that has the same radiative characteristics as the wing of Morpho butterfly by using the numerical method. To evaluate the radiative characteristics of the surface, a measurement system for bi-directional reflection of a surface has been developed. The system has two kinds of Laser, Ar ion and He-Ne and is capable of measuring the bi-directional reflection at four wavelength of 458 nm, 488 nm, 514 nm and 633 nm. By using the system, the radiative characteristics for the wing of "Morpho didius" instead of the predicted surface has been measured, because the surface could not be made. We are going to evaluate the present numerical method by comparing the measured results with the numerical predictions for radiative characteristics of the wing of Morpho didius.

本研究的目的是探讨通过在固体表面构建纳米结构来制造光学功能表面的可能性。在本研究的第一年，我们发展了一个预测奈米结构表面辐射特性的数值方法。该数值方法是求解麦克斯韦方程组的有限元方法，给出了具有纳米结构表面的物体对辐射的二维散射电场。该数值代码适用于具有多种纳米结构的表面。数值方法的适用性预测的表面与纳米结构的辐射特性已被证明。本研究的题目为“一种大斑蝶的辐射特性数值研究”，发表在《热科学与工程》上。“在第二年，我们通过使用数值方法预测了具有与Morpho蝴蝶翅膀相同辐射特性的表面纳米结构。为了评估表面的辐射特性，已经开发了一种用于表面的双向反射的测量系统。该系统采用Ar离子和He-Ne两种激光源，能够测量458 nm、488 nm、514 nm和633 nm四种波长的双向反射。利用该系统对“闪蝶”机翼的辐射特性进行了测量，由于无法制作机翼表面，因此没有得到预测的机翼表面。我们将评估目前的数值计算方法进行比较的测量结果与数值预测的辐射特性的Morphodidius的翅膀。
