Embodiment Construction

[0063] The specific implementation of the fully polarized supersurface carpet cloak is described in detail below with five embodiments, including the triangular split tip polarization-sensitive carpet cloak, the triangular split tip fully polarized carpet cloak, and the triangular split tip fully polarized illusion carpet Invisibility cloak, one-dimensional trapezoidal fully polarized carpet cloak and two-dimensional trapezoidal fully polarized carpet cloak. Among them, the triangular wedge, one-dimensional and two-dimensional trapezoidal platforms are all printed based on ABS-M30, and their length is P, cross-sectional inclination angle ψ, and width L. A metasurface cloak for wrapping wedges and trapezoidal platforms is designed using a flexible thin F4B board, and based on the above method, by synthesizing φ xy and alpha distribution for design modeling. Therefore, the carpet invisibility cloak of the present invention is a three-dimensional structure composed of ABS-M30 an...

Abstract

The invention belongs to the technical field of metasurface stealth, and particularly relates to fully-polarized metasurface carpet stealth garment based on a geometrical phase and a transmission phase and a design method of the fully-polarized metasurface carpet stealth garment. The carpet stealth garment is of any three-dimensional structure and is formed by splicing a plurality of planar metasurfaces. Each planar metasurface is formed by periodically extending a plurality of metasurface units; each metasurface unit comprises an upper-layer flexible dielectric plate, middle-layer engineeringresin and a lower-layer flexible dielectric plate, wherein one side of the upper-layer flexible dielectric plate comprises a metal arc electric resonator, the other side of the upper-layer flexible dielectric plate is fully corroded, and one side of the lower-layer flexible dielectric plate is fully metal while the other side is fully corroded; structural parameters and azimuth angles of the arcelectric resonator are changed along with different unit positions, and the arc electric resonator is designed through a full-polarization metasurface carpet stealth garment method. The carpet stealthgarment shows excellent electromagnetic stealth performance under the excitation of linearly polarized waves, circularly polarized waves or elliptically polarized waves with different polarization angles, and has the advantages of arbitrary polarization, arbitrary shape, excellent stealth characteristic, easiness in assembly and the like.

Description

technical field [0001] The invention belongs to the technical field of metasurface cloaking, and in particular relates to a supersurface carpet invisibility cloak capable of realizing perfect stealth characteristics under any polarized electromagnetic wave detection and a design method thereof. Background technique [0002] Invisibility has been a human dream for centuries, until the theory of transformation optics and the emergence of metamaterials made it possible. Based on the above two powerful tools, and by precisely tuning the constitutive parameters of anisotropic and heterogeneous bulk materials, perfect cloaking with hidden light / electromagnetic waves around the target becomes possible. Although the combination strategy of transformation optics and metamaterials is a fascinating way to achieve stealth, the large volume and exotic material parameters make it often difficult to realize in practical design. This problem was later alleviated to some extent by transmiss...
