SignificancePresently, metasurfaces have enabled full control of the electromagnetic waves thus leading to implementation of numerous applications such as flat lenses based on electromagnetic properties. Going with the current trends, future demand for efficient metasurfaces designs have attracted significant attention of researchers. Among the available metasurfaces, the reflective type, or called meta-mirror, enables full control of the reflected and scattered wavefronts. Unfortunately, for mo
