Paper Abstract

In this work, a metamaterial with 90°-twisted nanorods is presented and numerically investigated. Numerical simulated results demonstrate that our scheme can realize strong chiroptical response of the metamaterial to circularly polarized waves. We investigate circular dichroism in a bilayer chiral metamaterial in the optical range. The circular dichroism is very strong up to 75%. We also consider how the incident angle of the circular polarized wave affects the circular dichroism. We can achieve strong circular dichroism by changing the incident angle. The proposed metamaterial will be a good candidate for biosensing applications.
