摘要
Numeric encoding of metasurfaces can be seamlessly integrated with evolutionary algorithms to achieve intelligent design of metasurfaces. In this paper, we present a fully automated design approach for the design of reflective coding metasurfaces. In addition, we conduct a comparative performance study for three distinct evolutionary algorithms (i.e, BPSO, DE, and GA) in the optimization of two pixelized patterns corresponding to two coding units for a passive coding metasurface. Our investigations show that the BPSO algorithm achieves the most favorable performance for the design optimization task of coding metasurfaces under consideration.
