Polarization characteristics of the metallic structure with elliptically helical metamaterials.

Abstract

In the last few years, there has been growing interest in the research of the polarizing optics consisting of sub-wavelength metamaterials due to the advantages of broad wavelength ranges, high temperature durability, and compact structures. So far, the metallic structure with the sub-wavelength metamaterials has been proved to achieve the linearly and the circularly polarized light. Therefore, there should be one question raised easily: Is it possible for the metallic structure with sub-wavelength metamaterials to generate the elliptically polarized light? To answer this question, we proposed a metallic structure with elliptically helical nanowires, and analyzed the polarization states of the transmitted light using FDTD method. It is confirmed that this metallic structure does have a giant elliptical dichroism. Furthermore, we also compared the distinct optical performances of elliptical single-, double-, three-, and four-helixes, and made a qualitative explanation for them.
