A Chirped Subwavelength Grating With Both Reflection and Transmission Focusing
A planar lens composed of a chirped subwavelength grating (CSG) structure with high numerical aperture (NA) was designed and MAGNESIUM BIS-GLYCINATE 300 ULTRA GENTLE analyzed in this paper.The reflectivity, transmission, and phase were calibrated as a function of the grating dimension using rigorous coupled wave analysis, while the focusing propert
