Subwavelength grating metamaterial racetrack ring resonator (SGMRTR) increases the
coupling strength between the bus waveguide and the ring resonator and thus better …

Subwavelength grating metamaterial (SGM) waveguide is typically treated as a
homogeneous medium without considering intra-waveguide reflection. However, this …

A refractive index (RI) sensor with a high sensitivity based on an integrated double-layer
resonant meta-grating (DRMG) is theoretically demonstrated. The presented DRMG consists …

We proposed and experimentally investigated a two-ring-resonator composed planar hybrid
metamaterial (MM), in which the spectra of guided mode resonance (GMR) and Fano …

Mode volume overlap factor is one of the parameters determining the sensitivity of a sensor.
In past decades, many approaches have been proposed to increase the mode volume …

We have proposed a multi-band metamaterials composed of bars and planer SRR. There
are three sharp peaks in the transmission spectra in the visible and near-infrared region, we …

A refractive index (RI) sensor which contains a dielectric cavity composed of two parallel
planar waveguide gratings (WGGs) is proposed. Reflection and transmittance through …

In this paper, a racetrack ring resonator design based on a subwavelength grating double
slot waveguide is presented. The proposed waveguide scheme is capable of confining the …

In this letter, a guided-mode resonance (GMR) filter with the same material for both the
grating layer and the waveguide layer is designed, and its optical properties are …

Metamaterials (MMs) have shown huge potential in sensing applications by detecting their
optical properties, which can be designed to operate at frequencies from visible to mid-IR …
