T. J. Cui and co‐workers propose, on page 29, a new method to design planar dual‐functional devices using isotropic holographic metasurface, in which two different functions are written on the same hologram with no mutual coupling. Via specific design, double‐beam or double‐polarization radiating devices are realized independently by orthogonal excitations. Scanning radiating beams controlled only by frequency are demonstrated with different performances under orthogonal polarizations.
