Abstract

The mechanism of reflective electromagnetic metasurfaces has potential applications in information transfer and electromagnetic scattering suppression. In this article, the relation between the geometric entropy of the electromagnetic metasurface pattern and the scattering entropy of the metasurface is studied by introducing the power spectrum in the coding sequence generation, considering the correlation nature in the initial random geometric coding. The geometric entropy is found to generate an impact on the scattering form and scattering entropy of the 2 bit order random coding. The 2-D wideband power spectrum with central sunken is found to form the highest entropy in the scattering pattern. A metasurface sample is designed, prepared, and measured in the experiment to validate this theory. The results indicate another possible control parameter in entropy modulation, which has potential uses in multibeamforming and information transfer techniques.
