- Abstract
- A reflect-type metasurface with phase gradient discontinuity is proposed. It is formed by planar intertwined spiral conductors loaded with inductors. A pattern of conductors is initially designed under the assumption of locally periodicity and the phase response of uniform arrays. Simulations are performed with a fast proprietary code based on the periodic Method of Moment and the Array Scanning Method. Macro-cells, containing 70 identical micro-cells with different loads, have been analysed, and it is found that the reflected power only partially goes into the desired non-specular Floquet mode.
