Electromagnetic Reciprocal Cloak with Only Axial Material Parameter Spatially Variant

Figure 9

Electric field (𝐸_𝑍) distributions in the vicinity of the reciprocal cloak without perturbation (a), with positive perturbation (𝛿₂=1.1) while transverse parameters are invariant (𝛿₁=1) (b), impedances are invariant (𝛿₁=1.1) (c), and refraction index is invariant (𝛿₁=1/1.1) (d).
