In terahertz circular dichroism spectroscopy, efficient detection of circularly polarized light is strongly demanded. To improve the performance of circularly polarized light detection devices based on twisted carbon nanotubes, we investigated the effect of twisted structures on the circular dichroism of terahertz absorption using the FDTD method. The results demonstrated that optimizing the twisted structure can maximize the circular dichroism at specific frequencies, achieving high circular polarization selectivity. These findings will significantly contribute to the optimal structural design of such devices.
