الوصف: Active development is taking place in reconfigurable and static metasurfaces that control and optimize reflections. However, existing designs typically only optimize reflections from the metasurface panels, neglecting interference with reflections originating from supporting walls and nearby objects. In this study, we investigate how engineering the metasurface properties can modify the total scattering pattern, enabling the modification and optimization of reflections from significantly larger illuminated areas than the metasurface panel. To accomplish this, a general design approach is developed to create periodical metasurfaces with controlled reflection phase and amplitude for all propagating Floquet harmonics. By combining metasurface reflections with those from the surrounding walls, the total scattering can be manipulated. The study demonstrates how appropriately designed metasurfaces can modify reflections from surrounding walls, enhancing the functionalities of metasurfaces. These findings are intended to facilitate advancements in engineering and optimizing wave propagation channels, particularly for millimeter-wave communications.
