Novel air impedance matching material based on artificial metal microstructure unit and radome

Abstract

The invention relates to a novel air impedance matching material based on an artificial metal microstructure unit and a radome. The air impedance matching material comprises at least one material piece layer, each material piece layer comprises a substrate and an artificial metal microstructure arranged on the substrate, each substrate is virtually divided into multiple substrate units arranged in an array mode, two opposite surfaces of each substrate unit are respectively adhered to a first artificial metal microstructure and a second artificial metal microstructure, each first artificial metal microstructure is shaped like a strip, each second artificial metal microstructure comprises a connecting arm, two ends of each connecting arm extends to two sides of the connecting arm to form extending arms, and the free end of at least one extending arm extends to the other extending arm to form a bent arm. The novel air impedance matching material is good in impedance matching effect, small in reflection coefficient, small in overall thickness, simple in structure and easy to manufacture.

Description

technical field [0001] The invention relates to a material and a radome, in particular to a novel air impedance matching material and a radome based on an artificial microstructure unit. Background technique [0002] If the electromagnetic wave passes through materials with different impedances during transmission, it will be reflected at the interface. In order to reduce the reflection of electromagnetic waves and reduce energy loss, impedance matching needs to be considered in the transmission of electromagnetic waves. [0003] Metamaterial is a new type of artificial synthetic material, including an artificial microstructure with a certain pattern shape composed of metal wires and a substrate to which the artificial microstructure is attached. Multiple artificial microstructures are arranged in an array on the substrate. Playing a supporting role, it can be any material different from the artificial microstructure. The superposition of these two materials will produce an...
