“…And in the bent state, the peak of the first passband becomes two peaks. The reason is that when electromagnetic waves propagate back and forth in the substrate, they cannot avoid generating additional phases, which can cause destructive interference [32]. As the bending angle increases, this effect becomes more pronounced.…”

A flexible triple-band and polarization-insensitive rectifying metasurface (RMS) is presented in this article. The surface consists of three parts: a periodic metal unit with integrated diodes, a DC filter composed of series inductor and parallel capacitor, and a load resistor. Due to the direct integration of rectifying diodes and interconnected branches within and between the units, complex matching networks can be eliminated and the overall structure is simplified. A 6×6 array is fabricated and measured. The results show that at a low input power of 0 dBm, the RMS has efficiency of 51.81%, 44.25%, and 42.01% at 2.9 GHz, 5.2 GHz, and 5.77 GHz, respectively. The efficiency remains consistent under different polarization angles, demonstrating the polarization insensitivity property of RMS. Additionally, the flexible substrate enables high efficiency in the S-band and Wi-Fi bands even under a certain range of bending, revealing its superior flexibility and adaptability. Therefore, it is well suited for ambient energy harvesting and wireless self-powered miniaturized IoT devices.

Metasurfaces have attracted progressive attention as 2D metamaterials in recent years. Due to the ability to manipulate the phase, amplitude, and polarization of electromagnetic waves, metasurfaces have become a feasible way to control the wavefront. Here, two main platforms for exciting multi‐order diffraction beams in the far field based on metasurfaces, i.e., phase gradient metasurfaces (PGMs) and metagratings (MGs) are reviewed. First, the concept of generalized Snell's law (GSL) as well as the related works are presented. Then the connection between GSL and diffraction law is elaborated. The multi‐order diffraction methods based on the combination of the two principles are introduced. Following the discussion on several kinds of PGMs platforms for achieving multiple beams, the physical mechanisms of MGs are reviewed and recent progress is summarized. Finally, the typical challenges are outlined and the future development directions are prospected.
