Abstract

Directional control of radiation could be useful in a range of scientific and industrial applications. This study evaluated the possibility of directional control of radiation using nanofibers. Herein, scattering media containing directionally controlled nanofibers were assembled, and their relative directional radiative intensity was measured by constructing an optical system comprising a paraboloidal mirror and a charge-coupled device (CCD) camera. The influence of polarized light on relative light intensity was confirmed and compared to the theoretical result of a single nanofiber. The scattering direction of the scattered light was found to differ based on the material and size of the nanofibers. In addition, the scattering direction of the scattered light changed according to the incident angle of the irradiated light. Therefore, the results of this study suggest that radiation can be directionally controlled using a scattering medium containing nanofibers with controlled orientations.
