Metasurfaces enable almost complete control of light through ultrathin, subwavelength
surfaces by locally and abruptly altering the scattered phase. To date, however, all …

An angle-insensitive broadband absorber of graphene covering the whole visible spectrum
is numerically demonstrated, which is resulted from multiple couplings of the electric and …

Refractive index sensing is attracting extensive interest. Limited by the weak light–matter
interaction and the broad bandwidth of resonance, the figure of merit (FoM) of terahertz …

Ultrabroadband absorbers are vital for applications such as solar energy harvesting and
integrated optoelectronic devices. Herein, we design, fabricate and characterize a novel …

In this paper, we propose a terahertz (THz) guided-mode resonance (GMR) notch filter made

We present a systematic investigation on the enhancement of the quality (Q) factors for
guided-mode resonance (GMR) sensors with shallow subwavelength grating structures. By …

A compact, tunable guided-mode resonant filter (GMRF) is experimentally demonstrated
whose spectral reflectance wavelength varies as a function of the illumination position on …

Guided-mode resonance (GMR) sensors are an effective sensing technique for biomolecule
or gas molecule detection by monitoring the changes in the resonance wavelength …

Perfect absorption at a resonance wavelength and extremely low absorption at the
wavelength range of off-resonance in a one-port optical cavity is required for refractive index …

Guided-mode resonance (GMR) sensors are widely used as biosensors with the
advantages of simple structure, easy detection schemes, high efficiency, and narrow …
