Chiral Metamaterials: Giant Asymmetric Transmission and Circular Dichroism with Angular Tunability in Chiral Terahertz Metamaterials (Ann. Phys. 3/2020)

Chirality, as the core code of life forms, connects the ultimate secret of life and universe evolution. In article number 1900398, Changji Liu and co-workers propose an intrinsic chiral metamaterial and its complementary structures with coexistence of circular asymmetric transmission and circular dichroism in the THz region. The analysis reveals the chirality in metamaterials mainly comes from mode interaction and can be tuned by the incident angle. The results highlight the potential applications of these metamaterials in chiral sensing and polarization transformation devices with angular dependence.
