Broadband Design of Midinfrared Chiral Metamaterials Based on the Indium Tin Oxide Conical Helix
This paper proposed a periodic midinfrared broadband chiral structure composed of indium tin oxide (ITO) conical helix. The simulation results show that the structure achieves a good broadband CD in the midinfrared. At the wavelength of 9.2 μm, the maximum value of CD is 0.55, the FWHM (full width h...

| description | This paper proposed a periodic midinfrared broadband chiral structure composed of indium tin oxide (ITO) conical helix. The simulation results show that the structure achieves a good broadband CD in the midinfrared. At the wavelength of 9.2 μm, the maximum value of CD is 0.55, the FWHM (full width half maximum) of CD is 7.2 μm, and the wavelength range is from 5.7 μm to 12.9 μm. The simulation results also show that compared with the traditional uniform spiral structure with the same radius, the conical spiral structure can achieve better broadband circular dichroism in the midinfrared band. This provides a new idea for the design of broadband polarization state control devices in the midinfrared band. |
