Azimuth-Resolved Circular Dichroism of Metamaterials

Shuliang Ren et al.

Summary: In this study, experimental investigations were conducted on the azimuth-dependent circular dichroism (CD) spectra of achiral metamaterials, which showed good agreement with simulation results. The origin of the CD was explained by the coupling of macroelectric dipole and magnetic dipole, providing a potential method for constructing on-chip azimuth sensors based on CD spectra of metamaterials.

Shihao Li et al.

Summary: This article investigates the effects of the rotation angle between upper and lower n-fold rotational symmetric nano-structures. Various modes of circular dichroism in the wavelength band from 3.3 to 5 mu m are achieved. The sensitivity of circular dichroism to the rotation angle and the reconfigure strategy for opposite responses are discussed. The physical mechanism of mode's switching is explained using the Born-Kuhn model.

Biyuan Wu et al.

Summary: Chirality, as a fundamental property of nature, has potential applications in various fields. In this study, a novel plasmonic chiral metasurface with rectangular holes was systematically investigated, and it was found to exhibit strong circular dichroism in the near-infrared wavelength. The research also revealed the impact of the metasurface structure parameters and the rotation angle of the resonance units on circular dichroism. The chirality can be effectively regulated by changing the orientation of the units. Furthermore, simulations were conducted to reveal the underlying mechanism.
