▎ 摘　　要

NOVELTY - Ultra wideband transparent stealth supersurface comprises two unit structures with the same thickness, same period and reflecting phase satisfy 180±37℃, each unit structure comprises a multi-layer medium layer, a pattern layer, and a reflecting layer, the pattern layer is set between two adjacent medium layers, and the ultra-surface can generate RCS reduction in the broadband of the 3.5- 18 GHz. USE - The ultra-wideband transparent stealth super-surface is useful for cockpit observation glass, radio-frequency identification system, digital imaging and Fifth generation (5G) communication. ADVANTAGE - The super-surface has simple structure, mature processing technique and stable performance, and realizes the excellent single-station radar stealth performance and realizes diffuse reflection function of the reflected beam, thus reducing the probability of double station radar detection. The super surface has good transparency, polarization insensitive characteristics and incident angle stability. DESCRIPTION OF DRAWING(S) - The drawing shows (a)-(b) is in Example 1, compared with the same size metal plate, transparent invisible super-surface far field simulation scatter diagram of the 14.3 GHz. 1First dielectric layer 2Second dielectric layer 3Third dielectric layer 4Reflecting layer 5Pattern layer 6Reflecting layer
