Outline of Final Research Achievements

We developed a theoretical and numerical scheme for the elucidation of the optical properties of periodic ordered structures of soft matter, whose periodicity is of the order of a few hundred nanometers. We particularly focused on various structures exhibited by a chiral liquid crystal without mirror symmetry. By combining the above-mentioned scheme with numerical calculation of ordered structures by continuum theory, we obtained results that account almost perfectly for experimental results on various optical properties including optical microscope images and the dependence of reflection intensity on the incident angle and the polarization of the incident light.

Academic Significance and Societal Importance of the Research Achievements

周期的な構造を自発的に形成するソフトマターは,光学の観点からも興味を持たれている.そのような構造の光学的性質を明らかにするための理論的枠組み,計算手法の開発を行ない,種々の工学に関する問題に適用した.解像度の限界に近い数百nm程度の周期の構造がどのように光学顕微鏡で観測されるかは理論的に極めて難しい問題であり,光の電磁場に関する方程式を直接解くことでその問題に取り組み,光学顕微鏡の限界に近いところの動作の理解を与えたことに本研究の意義の1つがある.
