Teaser:
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.
Abstract:
Metasurfaces (MSs) have been utilized to manipulate different properties of electromagnetic waves. By combining local control over the wave amplitude, phase, and polarization into a single tunable structure, a multifunctional and reconfigurable metasurface can be realized, capable of full control over incident radiation. Here, we experimentally validate a multifunctional metasurface architecture for the microwave regime, where variable loads are connected behind the back plane to reconfigurably shape the complex surface impedance. As a proof-of-concept step, we fabricate several metasurface instances with static loads in different configurations (surface mount capacitors and resistors of different values in different connection topologies) to validate the approach and showcase the different achievable functionalities. Specifically, we show perfect absorption for oblique incidence (both polarizations), broadband linear-polarization conversion, and beam splitting, demonstrating control over the amplitude, polarization state, and wave front, respectively. Measurements are performed in the 4–18-GHz range inside an anechoic chamber and show good agreement with theoretically anticipated results. Our results clearly demonstrate the practical potential of the proposed architecture for reconfigurable electromagnetic wave manipulation.
