A new monolithic resonator metasurface design achieves ultra-high Q-factors while using only one resonator per unit cell. The metasurface relies on breaking the symmetry of otherwise highly symmetric resonators to induce intra-resonator mixing of bright and dark modes (rather than inter-resonator couplings), and is scalable from the near-infrared to radio frequencies and can be easily implemented in dielectric materials. The resulting high-quality-factor Fano metasurface can be used in many sensing, spectral filtering, and modulation applications.

The invention claims a terahertz band metamaterial sensor based on quasi-electromagnetically induced transparency (quasi-EIT) effect. The terahertz band metamaterial sensor comprises a dielectric layer and a metamaterial of a sub-wavelength metal array on the dielectric layer, wherein the sub-wavelength metal array is composed of a plurality of open circular resonant rings and open square resonantrings.
