Area instruction of Γ analysis and cloak characterization.
(a–c) Show the output images of “Ψ”. Area i and ii represent the exact area of “Ψ” and the background, respectively: (a) Cloak off and without the inner structure “ħ”. Cloak on and (b) without “ħ”/(c) with “ħ”. (d–f) Gaussian beam without “Ψ” mask. (d) Cloak off and with “ħ”. Cloak on and (e) without “ħ”/(f) with “ħ”. Cloak characterization. (1) Γ value comparison: Ψ structure (Γai,bi; Γai,ci) > output image (Γa,b; Γa,c) > background (Γaii,bii; Γaii,cii) ≈ hidden ħ (Γd,e; Γd,f). (2) Γ values peak at the 21 μm pitch of the output image and Ψ structure. (3) The fluctuation of Γ values on a low level represents the numerically well cloaked ħ.
