Enhanced structural tunability and high sensitivity of a THz metasurface absorber for precise automotive fuel characterization

Abstract This paper introduces a metasurface absorber (MSA) sensor designed for fuel adulteration detection in the sub-terahertz (THz) range. The MSA features mirror-symmetric separated half-circle (MSSHC)-shaped resonators, a gold ground plane, and a dielectric layer, operating effectively within t...
