Problems solved by technology
[0004] Generally speaking, for example, after the waveguide is filled with traditional dielectric materials, due to the change of the transmission wavenumber, the cut-off wavenumber is determined by the structural size of the waveguide. Therefore, after the waveguide is filled with the medium, the interference of the second-highest mode or even the higher-order mode will occur.

The invention relates to an X-waveband intelligent metamaterial wide-angle wave-transparent radome. The X-waveband intelligent metamaterial wide-angle wave-transparent radome comprises at least a metamaterial sheet layer, each metamaterial sheet layer comprises a first substrate and a plurality of artificial microstructures arranged on the first substrate in an array manner, the artificial microstructures are three hollow concentric quartered square-shaped structures, and four corners of an outer frame of each quartered square-shaped structure are connected in an entity manner. According to the X-waveband intelligent metamaterial wide-angle wave-transparent radome, the artificial microstructures in the specific shape are attached to the substrate, required electromagnetic response is obtained, the wave-transparent performance of the radome based on the metamaterial is enhanced, and the anti-interference ability is enhanced.
Description
technical field [0001] The invention relates to a radome, more specifically, to an X-band intelligent metamaterial large-angle wave-transmitting radome. Background technique [0002] Metamaterials, commonly known as metamaterials, are a new type of synthetic material, which is composed of a substrate made of non-metallic materials and multiple artificial microstructures attached to the surface of the substrate or embedded in the interior of the substrate. The substrate can be virtually divided into multiple substrate units arranged in a rectangular array. Each substrate unit is attached with artificial microstructures to form a metamaterial unit. The entire metamaterial is composed of many such metamaterial units, just like Crystals are composed of countless crystal lattices arranged in a certain way. The artificial microstructures on each metamaterial unit may or may not be identical. Artificial microstructures are planar or three-dimensional structures with certain geome...
