“…The introduction of multilayer metal resonant structures is another more complex metasurface development strategy. [30,34] Compared with the transversely anisotropic meta-atoms, the multilayer meta-atoms mainly increase the independent EM response through the longitudinal combination of resonators with different shapes and sizes. Therefore, multilayer metasurface can maintain richer phase responses without sacrificing polarization properties but put forward higher requirements for design and manufacturing.…”

Metasurface reveals distinguished application prospects profiting from its excellent manipulating capacity for electromagnetic (EM) wave using ultrathin thickness and the simple design method. Easy to conformal metasurface with high performance and integrated EM functions is highly in demand in many EM devices. Herein, an arched dual‐wavelength cloaking–illusion‐integrated metasurface consisting of two‐layer meta‐atoms is proposed successfully. A composite‐fused deposition molding packaging strategy of additive manufacturing is explored to fabricate the multilayer structures for metal meta‐atoms and dielectric substrates simultaneously. Simulation and measurement results show that the arched metasurface possesses polarization‐insensitive cloaking and illusion functions in 4.3–4.8 and 14.8–16.3 GHz, respectively. The effective incidence angle range covers from −45° to 45°. The excellent EM camouflage performance proves the effectiveness of our design and fabricating strategy, which paths a way for multifunctional metasurface‐based devices.

“…[ 1 ] Various methods have been regarded, so far, to obtain invisibility and cloaking that includes using engineered materials such as photonic crystals (PhCs) and metamaterials, merging metasurfaces, and zero index (ZI) structures, overlaying the real and imaginary view points by using optical elements, scattering cancellation, and applying the transformation optic techniques. [ 2–6 ] The cloaking condition is fulfilled by the wave propagation and its phase fronts tailoring. The cloaked object does not need to be isolated from the environment, provided that the scattered wave is penetrable in the hidden object.…”

Here, a two-dimensional (2D) hole-type square lattice photonic crystal is shown to achieve invisibility cloaking based on all-angle self-collimation. The proposed structure, which is composed of the high-refraction-index dielectric material PbTe (n PbTe ≈ 6), is applicable in the mid-infrared (mid-IR) frequency range. The cloaking region is capable of hiding any object of any shape and size since the incoming wave does not interact with the cloaked object. The optimization process and the functionality of the proposed structure are investigated by equal frequency contour analysis and the finite difference time domain (FDTD) method.
