Area of Science:

  • Metasurfaces
  • Terahertz (THz) technology
  • Nanophotonics

Background:

  • Bound states in the continuum (BICs) offer high Q-factors but are typically difficult to excite.
  • Metasurfaces provide a platform for manipulating electromagnetic waves at the nanoscale.
  • Terahertz sensing requires sensitive and selective detection methods.

Purpose of the Study:

  • To demonstrate a double-strip array (DSA) metasurface supporting sharp quasi-BICs in the terahertz region.
  • To investigate the tunability of BICs and quasi-BICs by altering structural parameters.
  • To evaluate the potential of the DSA metasurface for sensing applications.

Main Methods:

  • Numerical simulations were performed to design and analyze the DSA metasurface.
  • The Q-factor and bandwidth of quasi-BICs were calculated based on structural parameters.
  • The influence of substrate properties (refractive index, absorption) on optical response was studied.
  • Sensing performance was assessed by simulating the frequency shift upon introducing a thin membrane layer.

Main Results:

  • A maximum Q-factor exceeding 500 was achieved for quasi-BICs with a bandwidth below 1 GHz.
  • Resonant frequencies showed a linear decrease with increasing substrate refractive index.
  • A sensitivity of 87.5 GHz/RIU was demonstrated for molecular detection using a 10 μm membrane.
  • Low-loss substrates and specific material absorption properties enhance Q-factors.

Conclusions:

  • The DSA metasurface effectively supports sharp quasi-BICs with tunable properties.
  • The metasurface exhibits high sensitivity and Q-factors, suitable for terahertz sensing.
  • Careful selection of substrate materials is crucial for optimizing sensing performance.
