Embodiment Construction

[0023] The present invention provides a metamaterial radome, comprising at least one metamaterial sheet 1, such as figure 1 with figure 2 shown. Each metamaterial sheet 1 includes two opposite substrates and an array of artificial microstructures attached between the two substrates, and each artificial microstructure includes a plurality of cross-shaped structures. When there are multiple metamaterial sheets 1, each metamaterial sheet 1 is superimposed along the direction perpendicular to the sheets, and assembled into a whole by mechanical connection, welding or bonding, such as figure 2 shown.

[0024] image 3 A schematic diagram (perspective view) of the structure of a metamaterial sheet is shown. The metamaterial sheet 1 includes two identical sheet-like substrates of equal thickness: a first substrate 10 and a second substrate 20 oppositely arranged, and an array row is attached on the surface of the first substrate 10 facing the second substrate 20. Artificial Mi...

Abstract

The metamaterial antenna cover comprises at least one metamaterial lamella, each metamaterial lamella comprises a first base plate and a second base plate which are arranged oppositely, a plurality of artificial microstructures are arranged in array between the first base plate and the second base plate, and each artificial microstructure includes a plurality of cross structures. According to the metamaterial antenna cover, the artificial microstructures in specific shapes are attached to the base plates to obtain required electromagnetic response, therefore wave transmission performance of the antenna cover based on a metamaterial is increased, and antijamming capability is improved.

Description

technical field [0001] The present invention relates to radomes, and more particularly, to metamaterial radomes. 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 geometric figures composed of metal wires, su...
