Phase-controlled metasurface design via optimized genetic algorithm

Phase-controlled metasurface design via optimized genetic algorithm

In an optical Pancharatnam-Berry (PB) phase metasurface, each sub-wavelength dielectric structure of varied spatial orientation can be treated as a point source with the same amplitude yet varied relative phase. In this work, we introduce an optimized genetic algorithm (GA) method for the synthesis...
