Multiple Fano resonances in all-dielectric elliptical disk-ring metasurface for high-quality refractive index sensing
In this study, an all-dielectric metasurface is proposed, whose unit cell is composed of a silicon elliptical disk and a silicon elliptical ring. The transmission of the structure were analyzed by using three-dimensional finite-difference time-domain method. In the wavelength range of 800 to 1200 nm...
