The emergence of the metasurface has provided a versatile platform for manipulation light at nanoscale. Recent research in metasurfaces explored plethora dynamic control and switching multifunctionalities, paving way innovative applications fields such as imaging, sensing, communication. However, current multifunctional face challenges terms functional scalability selective activation. In this work, we introduce experimentally demonstrate strategy that utilizes multiple plane waves to create arbitrary periodic patterns on metasurface, thus enabling spatial-selective activation its embedded multiplexed functionalities. Furthermore, our facilitates through mechanical translation, demonstrated by high-speed, dynamically switchable beam deflection scenario. Our method effectively overcomes limitations associated with traditional spatially multiplexing techniques, offering greater flexibility selectivity metasurfaces.
