Abstract
A novel mathematical approach is proposed for the placement of unit-cells at digital metasurfaces with applications in holography, imaging, coverage improvement and antenna array. As a proof of concept, the idea is applied to a simple unit-cell capable of providing 180 degrees of phase difference between two states of it. Used unit-cell is working at 90GHz although the idea can be used in any other frequencies. It has been shown that the proposed method is capable of providing better results compare to conventional techniques in terms of concentration of intensity and quality of produced field pattern.
