The binary phase profiles of the coding metasurface for different holographic images. The binary holograms for a sequence of letters of ‘LOVE PKU! SEU! NUS!’ are generated by the modified GS algorithm that could be realized by switching the states of corresponding unit cells of the coding metasurface
