“…The metastructures are an ultrathin two-dimensional planar device composed of arrays of sub-wavelength structures, that can be classified as metal or dielectric [1,2]. The metal metastructures are affected by the inherent strong ohmic loss and saturation effect and the figure of merit (FOM) for metallic materials sensors is limited [3][4][5]. The dielectric metastructures make it possible for Fano resonances with high Q-factors to be achieved more easily due to the avoidance of ohmic losses [6][7][8].…”

In this paper, an all-dielectric metastructure-based high-contrast refractive index sensor is proposed. This structure can be utilized to detect various concentrations of glycerol-water mixtures by evaluating transmission spectral lines and resonant wavelength shifts related with liquid concentration detection. The experimental and calculated results of the developed sensor structure are able to excite three resonance peaks, demonstrating that the structure is capable of reaching excellent sensing capabilities. It has been established that this work has the potential to be useful in medical and biological detection; this is of great scientific and practical significance.
