Abstract
The semi-shell structures are attractive composite nanomaterials with properties such as optical anisotropy and large absorption cross sections. In this study, to evaluate the optical characteristics for the optical geometry of the semi-shell structure, we analyzed the scattered light spectrum using the propagation type surface plasmon. As a result of the measurement, the difference of the spectrum was observed depending on the optical geometry of the semi-shell structures. In addition, we confirmed their structures by FE-SEM observation of the measured structures, and evaluated the optical properties related to the optical geometry of the structure by performing FDTD simulation. From the experimental and numerical results, we evaluated statistical data on the orientation of the structure within a certain range. We could show the positive effect of the surface modified substrate to control the orientation of the semi-shell structures.
