Outline of Final Research Achievements

The purpose of this study is to investigate the anisotropic dichroism arising from submicrometer-scale hemispherical structures covered with a thin metallic layer from an application perspective for sensor chips. In the study period, the optimized conditions of the hemispherical structures could be found to generate obvious extinction spectrum in the optical reflection and to generate large shift of the extinction spectrum peak according to the ambient refractive index changes. The spectrum peak shift was associated with the dielectric dispersions of both the thin metallic layer and ambient medium. In addition, a functional structure based on the spherical structure, barnacle-like porous structure, was also realized by using the colloidal particles.
