▎ 摘　　要

NOVELTY - Multi-layer artificial structure wave-absorbing material comprises a metal back plate, a multiple array wave absorbing units arranged on the metal back plate. The wave absorbing unit comprises a six-layer dielectric layer and a five-layer annular resistance pattern. A layer of annular resistors pattern is clamped between two adjacent layers of dielectrics. The center of the five layer of the ring is projected onto the metal board and distributed in the ring with a diameter of 5 mm. The outer ring is a ring-shaped ring, and the width of the inner ring is w, and L is 10 mm and less than or equal to 20 mm. USE - The multi-layer artificial structure wave-absorbing material is useful in information transmission, electronic device, microwave radiation protection and civil fields, smart home, mobile phone, bracelet, Bluetooth (Wireless data communications protocol) earphone, automobile electronic, automatic driving radar, and research and production test. ADVANTAGE - The multi-layer artificial structure wave-absorbing material has good wave absorbing effect in wide frequency range, satisfies requirement of people for broadband wave absorbing material, has simple operation, is good for industrial production, achieves good impedance matching effect, and reaches high-strength absorption in Ultra wideband (UWB) by increasing loss of the electromagnetic wave. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing multi-layer artificial structure wave-absorbing material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of multilayer artificial structure absorbing material.
