    Terahertz Circular Dichroism Spectroscopy of 3D Chiral Metallic Microstructures Fabricated Using High Precision CNC Machining by Atsushi Ouchi, Saroj R. Tripathi

    Published 2025-01-01
    “…The helix array converts linearly polarized light into circularly polarized light from 120 GHz to 200 GHz, with a 3 dB axial ratio relative bandwidth approaching 50%. The polarization extinction ratio is in excess of 20 dB. These outstanding features, combined with their low cost, high accessibility, as well as their potential for mass production, pave the way for development of diverse range of optical components such as polarizers, filters, absorbers, and isolators operating in the terahertz frequency region.…”
