## Abstract We describe a design methodology for synthesizing diffractive elements based on twoβdimensional subwavelength cylindrical microstructures. We combine a numerical and experimental approach to demonstrate that by varying the diameter, pitch, and depth of subwavelength cylindrical occlusio
