چکیده
In this paper, a metamaterial absorber with checkerboard patterned ITO (indium tin oxide) film as the surface is obtained by using flexible and optically transparent wave-absorbing material ITO–PET (polyethylene terephthalate), coding arrangement of two basic units based on APS-PSO (Array Pattern Synthesis -Particle Swarm Optimization) algorithm. The structure consists rectangular patch structures circular (110 Ω/sq). are symmetrical. middle layer made up layers PET one PMMA, bottom covered low square resistance (8 experimental results, which consistent simulation show that has superior performance: over 90% absorptance in 5.06–9.01 GHz band, high transmittance, −10 dBsm RCS (radar cross-section) reduction 5.3–8.7 band. This design also polarization insensitivity angular stability.

We demonstrate a broadband, polarization independent, wide-angle absorber based on a metallic metasurface architecture, which accomplishes greater than 90% absorptance in the visible and near-infrared range of the solar spectrum, and exhibits low absorptivity (emissivity) at mid- and far-infrared wavelengths. The complex unit cell of the metasurface solar absorber consists of eight pairs of gol...

متن کاملField-programmable beam reconfiguring based on digitally-controlled coding metasurface
Digital phase shifters have been applied in traditional phased array antennas to realize beam steering. However, the phase shifter deals with the phase of the induced current; hence, it has to be in the path of each element of the antenna array, making the phased array antennas very expensive. Metamaterials and/or metasurfaces enable the direct modulation of electromagnetic waves by designing s...
