Design and verification of a high-Q, high-sensitivity, multi-mode metasurface and measurement of its clothing fabric sensing performance
A multi-mode resonant metasurface based on asymmetry is verified and optimized in the 1.0–16.0 THz range. Two toroidal dipole modes (ETD1 and ETD2) with high Q values and high sensitivity are revealed by this asymmetry metasurface, which demonstrates resonant characteristics different from traditional metamaterials/met...
