Abstract
An ultrathin metasurface-based polarization-insensitive single-band terahertz (THz) sensor comprising graphene concentric rings and a thin layer of MXene was investigated for the human body cancer cells detection. The overall metamaterial configuration exhibits single narrow-band nearly-perfect absorption with a high value of quality factor due to a full-width-half-maximum of 0.033 THz at the resonance frequency of 3.793 THz. The results show a high sensitivity of the metamaterial configuration along with a stable operation under different incidence polarizations. The results reveal the designed structure is of potential in biomedical applications.
