The expression dϕj/dR determines how a little change in a nanorod radius will introduce a modify from the regional period at wavelength λj and will be decided numerically using the section map Fig. 1(d). However, the cost gradient profiles obtained at this time aren't circularly symmetric. A median procedure is then executed to ensure metasurface round symmetry by dividing a metasurface into concentric rings centered with the optical axis with ring width equal for the meta-atom pitch; a median of Price perform gradients weighted by full intensity (summed around all sampling fields and wavelengths) illuminated on Each individual position inside of a ring is used and rod radius profiles are current appropriately.
