Abstract

The invention belongs to the technical field of metasurface cloaking, in particular to a fully polarized metasurface carpet cloak based on geometric phase and transmission phase and a design method thereof. The carpet invisibility cloak of the present invention is an arbitrary three-dimensional structure, composed of multiple planar metasurfaces spliced ​​together; the planar metasurface is composed of several metasurface unit periodic extensions; each metasurface unit includes an upper layer of flexible dielectric board, a middle layer of engineering resin and a lower layer of flexible media The upper flexible dielectric plate contains a metal arc electric resonator on one side, and the other side is fully corroded; the lower flexible dielectric plate is all metal on one side, and the other side is fully etched; the structural parameters and azimuth angles of the arc electric resonator vary with the location of the unit. Change, design by the fully polarized metasurface carpet cloak method; the carpet cloak of the present invention all shows superior electromagnetic stealth performance under the excitation of linearly polarized waves, circularly polarized waves or elliptical polarized waves of different polarization angles, And it has the advantages of arbitrary polarization, arbitrary shape, excellent stealth characteristics and easy assembly.

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...
