(a) 3D schematic of the full cloak design consists of radially arranged 36 fins. The inner and outer radii are and , respectively. (b) Magnified view of the fin structure made of polymer core sandwiched between InSb cladding layers. The thickness of the InSb and the width of polymeric fin vary along the radius.

The simulation results under a 1 THz frequency Gaussian beam incidence. (a), (b), and (c) are the spatial distribution magnetic field magnitude, magnetic energy distribution, and profile of magnetic energy cross section of the PEC cylinder, respectively. (d), (e), and (f) are the ideal cloaking case (theoretical continuous parameters in Fig. 2(c)); (g), (h), and (i) are the realistic case with fins; (j), (k), and (l) are fin design without InSb coating, compared to (a), (b), and (c), respectively.
