Abstract: Digital-coding metasurfaces provide a convenient method for designing metasurface-based functional devices. By delicately arranging the coding sequences, electromagnetic fields on the metasurfaces can be modulated for applications like wave-front engineering, amplitude controlling and polarization conversion.…
