摘要：
A single-layer metasurface based on the element-group which consists of two similar unit cells is proposed in this paper. The element-group can cover the phase shift range of more than 360 degrees with transmission efficiencies over -3 dB. Also a metasurface focusing lens working at 11GHz is built for medical applications. The presented simulation results show that the electromagnetic power can be focused on a spot in the near-field.
