1. A lightweight absorption-transmission integrated metamaterial to electromagnetic waves with polarization stability and wide-incident-angle stability, wherein the lightweight absorption-transmission integrated metamaterial is a symmetrical structure comprising at least one square frequency-selective structure-unit arranged periodically;
a side length of each of the at least one square frequency-selective structure-unit is 50 mm; each of the at least one square frequency-selective structure-unit comprises a first dielectric substrate, a metal array structure layer, a second dielectric substrate, a first carbon-based conductive film array structure layer, a third dielectric substrate, and a second carbon-based conductive film array structure layer laminated in sequence, the first dielectric substrate serves as a bottom layer, and the second carbon-based conductive film array structure layer serves as a top layer;
the metal array structure layer is configured as a frequency-selective-transmission layer, and is made of a metal patch;
the first carbon-based conductive film array structure layer and the second carbon-based conductive film array structure layer are each configured as a frequency-selective-absorption layer, and are both made of a carbon-based conductive film patch;
the metal array structure layer is formed by a basic-structure-unit composed of four square ring apertures arranged periodically;
the first carbon-based conductive film array structure layer comprises a basic-structure-unit composed of a cross-shaped structure patch; and
the second carbon-based conductive film array structure layer comprises a basic-structure-unit composed of four square ring patches arranged periodically.
