(a) Three-dimensional and (b) two-dimensional display of theoretical results of the object wave in the far field; (c) three-dimensional demonstration of the full wave simulation result of the object wave in CST software; (d) demonstration of the object wave in the two principal planes of the hologram. Note that the first plot of (d) is demonstrated in X′Z′-plane and the later plot is shown in the plane which is perpendicular to X′Z′-plane and contain the main beam direction that the peak gain occurs (i.e., θ = 20°, where θ is the polar angle in XYZ coordinate system).
