Abstract

The invention relates to the field of electromagnetic stealth technology and radiation protection, and discloses a net-shaped layered-structure electromagnetic wave absorbing metamaterial. The electromagnetic wave absorbing material comprises: a first member (10) which at least includes one type of transparent flexible polymer materials and serves as an outer casing; a second member (20) which at least includes one type of flexible polymer materials and serves as a filling material between two metallic layers; a third member (3) which at least includes one type of metallic net-shaped structure and serves as a resonance net-shaped unit array. The third member (3) may adopt one type of metallic materials and may adopt plural metallic materials, and even alloy materials. The first member, the second member and the third member can all have many groups and form a multi-layered metamaterial structure. The layered-structure absorbing metamaterial of the invention increases absorbing width of electromagnetic waves and expands application range of the layered-structure absorbing metamaterial.

Description

technical field [0001] The invention relates to the technical field of electromagnetic cloaking, in particular to a mesh layered electromagnetic wave absorbing metamaterial. Background technique [0002] With the development of science and technology, the electromagnetic pollution caused by the large increase in the use of electronic products has seriously affected people's health and the natural environment. In recent years, more and more people have begun to pay attention to the problem of electromagnetic pollution, and electromagnetic shielding materials and electromagnetic wave absorbing materials have also emerged as the times require. Among them, absorbing materials can effectively absorb electromagnetic radiation and reduce electromagnetic interference. Compared with electromagnetic shielding materials, they have a broader application market because of their high efficiency and universality. On the other hand, modern warfare also increasingly involves the field of st...
