Multifunctional Metasurface Architecture for Amplitude, Polarization and Wave-Front Control

Metasurfaces could have transformational impact on emerging applications, from smart antennas and 6G communication to the Internet of Things and wireless power transfer, thanks to their ultracompact dimensions and tailored designs. To fully realize this potential, metasurfaces that can implement different functionalities and dynamically switch between them are desired. This study presents a multifunctional microwave metasurface architecture that incorporates electronic components within the unit cell to exert control over the metasurface's response. Bridging applied physics and device engineering, this work is a concrete step toward readily deployable and versatile metasurface technology.
