Embodiment Construction

[0025] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings. These embodiments are only used to illustrate the present invention, and are not intended to limit the protection scope of the present invention.

[0026] like figure 1 Shown is a surface creeping wave absorbing coating structure of the present invention, which is coated on the surface of the target 10, and the coating structure includes a wave-absorbing layer 20 and a conductive reflective layer bonded from the inside to the outside of the target 10 surface. Layer 30, the wave-absorbing layer 20 can absorb and convert the electromagnetic waves crawling on the surface of the target (i.e., the surface crawling waves 40) into heat energy, and the conductive reflective layer 30 has a reflection effect, which can suppress the external radiation of the crawling electromagnetic waves entering the wave-absorbing layer ; The material of the wave-abso...

Abstract

The invention discloses a surface creeping wave absorption coating structure, which is coated on a target surface. The coating structure comprises a wave-absorbing layer and an electric conduction reflection layer, wherein the wave-absorbing layer and the electric conduction reflection layer are bonded from inside to outside on the target surface; the wave-absorbing layer can adsorb target surface creeping electromagnetic wave and convert the target surface creeping electromagnetic wave into thermal energy; the electric conduction reflection layer has a reflection function, can inhibit the creeping electromagnetic wave which enters the wave-absorbing layer from outwards radiating; and the material of the wave-absorbing layer has impedance characteristics to cause the creeping electromagnetic wave to enter the wave-absorbing layer as many as possible. By use of the surface creeping wave absorption coating structure provided by the invention, the surface creeping electromagnetic wave can be thoroughly eliminated so as to greatly lower the influence of the creeping wave on antenna, and high efficiency of the antenna is guaranteed. In addition, the thickness and the width of the coating are greatly reduced than those of a conventional coating, and the structure is suitable for a wide surface creeping wave adsorption situation.

Description

technical field [0001] The invention aims at the technical field of surface creeping wave elimination related to electromagnetic scattering and electromagnetic compatibility in military or civilian use, and specifically relates to a surface creeping wave absorbing coating structure. Background technique [0002] When the electromagnetic wave is incident on the target surface at a small angle, it will form an electromagnetic wave crawling along the target surface, which will bring new problems such as electromagnetic scattering and electromagnetic interference. Especially in the military, due to the existence of discontinuous features on the surface of equipment, such as edges, sharp points, gaps, steps, and discontinuous edges of the medium, surface crawling electromagnetic waves will form weak scattering centers when encountering these discontinuous features. When the main scattering source After being suppressed, the backscattering intensity of these scattering centers may...
