Simulations of the achromatic optical virtual shaping.
(a), Schematic of the three dimensional model. The metallic bars are shown with different colors. The incident electric fields for the TE and TM polarizations are depicted. (b), Calculated RCS of a sample with apertures of 8 μm × 8 μm. (c), Calculated diffraction patterns in the k-space for a planar metallic plate (the first column), a phased plate with dimensions of 8 μm × 8 μm (the second column) and a phased plate with dimensions of 40 μm × 40 μm (the third column).
