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 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 focusi...
