OPTICALLY TRANSPARENT DIFFUSE REFLECTION WAVE ABSORBER CAPABLE OF ABSORBING AND SCATTERING ULTRA-WIDEBAND MICROWAVES

WIPO Patent Application WO/2023/160435

A1

The present invention relates to an optically transparent diffuse reflection wave absorber, and provides an optically transparent diffuse reflection wave absorber capable of absorbing and scattering ultra-wideband microwaves. The present invention aims to solve the problems of a narrow absorption band and low absorption frequency band coincidence of existing diffuse reflection wave absorber composition units. The optically transparent diffuse reflection wave absorber is sequentially composed of, from top to bottom, an upper-layer patterned conductive film layer, a first transparent substrate, a first dielectric layer, an intermediate-layer patterned conductive film layer, a second transparent substrate, a second dielectric layer, a bottom low-impedance conductive film layer, and a third transparent substrate; the upper-layer patterned conductive film layer is composed of N×M impedance film units; and the N×M impedance film units are composed of first absorption units and second absorption units. The present invention is used for the optically transparent diffuse reflection wave absorber capable of absorbing and scattering ultra-wideband microwaves.
