Abstract

The invention discloses a high-transparency diffuse reflection metasurface based on a regular hexagon arrangement circular ring mesh. The technical problem that in the prior art, diffuse reflection metasurface transparency is low is solved. The metasurface comprises a transparent dielectric plate and M*N periodically arranged coding units printed on the upper surface of the transparent dielectricplate, the lower surface of the transparent dielectric plate is printed with a mesh composed of a plurality of circular ring patches, which are arranged in a regular hexagon manner and stacked in thewidth direction; each coding unit comprises K*K first coding subunits and second coding subunits, which are periodically arranged; the two coding subunits adopt a circular mesh structure consisting ofa plurality of circular ring patches, which are arranged in a regular hexagon manner and stacked in the width direction; rectangular notches with the same width and different depths are etched in theintersection positions of two orthogonal diameters and the circumference of the circular mesh structure, the number and the positions of the two coding subunits are determined through the optimal coding sequence, and the size is determined by the phase difference of 180 +/-30 degrees in the reflection characteristic.

Description

technical field [0001] The invention belongs to the technical field of artificial electromagnetic materials, and relates to a diffuse reflection metasurface, in particular to a highly transparent diffuse reflection metasurface which reduces the radar scattering cross section, which can be used for reducing the radar scattering cross section of an optically transparent window. Background technique [0002] Metasurface is an anisotropic quasi-periodic two-dimensional artificial electromagnetic metamaterial on the subwavelength scale. By designing the structure of subwavelength units and adjusting their arrangement, the state of electromagnetic waves can be flexibly adjusted, such as electromagnetic wave reflection or transmission. Free adjustment of characteristics such as phase, polarization mode, and propagation mode. Common electromagnetic metasurfaces mainly include frequency selective surfaces, electromagnetic bandgap structures, metamaterial absorbers, phase gradient met...
