“…So, independent manipulation of dual‐band orthogonal‐LP reflection can be simply realized by placing x ‐pol and y‐ pol subunits orthogonally. [ 25 ] The specific frequency quantitative customization method for simply expanding the two separated bands of x ‐pol and y‐ pol subunits is described in the Supporting Information. As shown in Figure a, a variant Jerusalem cross etched on the dielectric substrate (orange: metal, gray: dielectric substrate) is used as the orthogonal‐LP subunit (denoted as Element A).…”

“…In recent years, metasurface-based highly integrated multichannel multiplexing (e.g., frequency-polarization multiplexing) is the general trend for modern wireless communication to realize high information capacity. [19] Many metasurface-based OAM generator have been proposed, which are realized by singlepolarization frequency multiplexing, [20,21] single-band polarization multiplexing, [22,23] dual-linearly polarized (LP) dual-band techniques, [24,25] dual-circularly polarized (CP) dual-band techniques, [26,27] as well as active components loading. [28,29] Nevertheless, these metasurfaces are limited by LP-only or CP-only modulation, which neglect the joint multiplexing of LP-OAM and CP-OAM to further enhance channel capacity.…”

physical degrees-of-freedom (Dof ) for EM wave. [2] Accordingly, OAM technology has attracted much attention in the fields of optics, [3] terahertz, [4] millimeter-wave, [5] and microwave [6] communications. However, the conventional OAM generation devices (e.g., spiral phase plates, [7] phased array [8] ) are difficult to integrate multiple Dof of EM waves, which cannot meet the demand of high information capacity for satellite communication [9] (SatCom) on-the-move, [10] supermassive multipleinput multiple-output (SM-MIMO), [11,12] and physical layer security in 6G. [13,14] Metasurfaces show great flexibility in manipulating the amplitude, phase, and polarization state of EM waves, making them excellent platforms for vortex beam generation, [15] holography imaging, [16] beam convergence, [17] beam scanning, [18] etc.. In recent years, metasurface-based highly integrated multichannel multiplexing (e.g., frequency-polarization multiplexing) is the general trend for modern wireless communication to realize high information capacity. [19] Many metasurface-based OAM generator have been proposed, which are realized by singlepolarization frequency multiplexing, [20,21] single-band polarization multiplexing, [22,23] dual-linearly polarized (LP) dual-band techniques, [24,25] dual-circularly polarized (CP) dual-band techniques, [26,27] as well as active components loading. [28,29] Nevertheless, these metasurfaces are limited by LP-only or CP-only modulation, which neglect the joint multiplexing of LP-OAM and CP-OAM to further enhance channel capacity. Subarray, [30] radial stitching, [31] and multilayer [19] techniques have been used to achieve independent multiplexing of LP and CP in two different bands. Nonetheless, the commonly used Pancharatnam-Berry (PB) phase meta-atoms for CP channel rely on dynamic rotation to manipulate wavefront, which tend to compress the available space of the lattice and are prone to footprint collisions with LP subunits. The last two year studies on noninterleaved metasurface [32] and chiral-assisted geometric-phase metasurface [33] also have the unavoidable dynamic rotational properties of the meta-atoms. So, the CP and LP subunits of current multifunctional metasurfaces can only be staggered on a single-layer lattice to avoid collision with each other, which is Metasurface is extensively studied for generating multicharacteristic orbital angular momentum (OAM) beams. However, designing a highly integrated and independent polarization-frequency multiplexing metasurface for efficient multiscenario OAM-related applications is still a challenge. Here, a triple-band single-layer shared aperture reflective metasurface for triple-polarization channels independent OAM modulations is proposed. The specific frequency quantitative customization resonance phase and quasi-static geometric phase are utilized to manipulate the dualband (Ku-and K-band) orthogonal linearly polarized (LP) channel and C&Xband right-handed circularly polarized (RHCP) channel. An isolation ring is introduced for eliminating t...

Abnormal refraction and reflection refers to the phenomenon in which light does not follow its traditional laws of propagation and instead is subject to refraction and reflection at abnormal angles that satisfy a generalization of Snell’s law. Metasurfaces can realize this phenomenon through appropriate selection of materials and structural design, and they have a wide range of potential applications in the military, communications, scientific, and biomedical fields. This paper summarizes the current state of research on abnormal refractive and reflective metasurfaces and their application scenarios. It discusses types of abnormal refractive and reflective metasurfaces based on their tuning modes (active and passive), their applications in different wavelength bands, and their future development. The technical obstacles that arise with existing metasurface technology are summarized, and prospects for future development and applications of abnormal refractive and reflective metasurfaces are discussed.
