Field-programmable beam reconfiguring based on digitally-controlled coding metasurface [PDF]
Scientific Reports, 2016 AbstractDigital phase shifters have been applied in traditional phased array antennas to realize beam steering. However, the phase shifter deals with the phase of the induced current; hence, it has to be in the path of each element of the antenna array, making the phased array antennas very expensive. Metamaterials and/or metasurfaces enable the direct
