Abstract
Achieving higher sensitivity in THz metasurfaces requires a larger Q-factor to minimize losses. EIT-like and perfect absorber metasurface can reduce losses and gain higher sensitivity. Here, we designed a novel THz absorber metasurface and its EIT-like counterpart and compared their sensing performance. Using EM simulation and varying the sample's refractive index, a theoretical sensitivity of 842GHz/RIU and 560GHz/RIU achieved for absorber and EIT-like metasurface, respectively. These findings validate the effectiveness of both biosensors, with absorbers showing greater potential for biosensing.
