MetaTune

The evolving needs of society demand advanced control of electromagnetic waves. At the forefront of science are metasurfaces—ultrathin engineered layers with tailored electromagnetic responses. While traditional metasurfaces are statically predesigned, current research is shifting toward reconfigurable metasurfaces, which can dynamically adjust their properties after fabrication. This capability expands their potential for real-world applications across a range of industries. Despite their promise, most reconfigurable metasurfaces rely on the element-by-element tunability of large arrays that require high energy consumption, complex implementation, and high costs. MetaTune addresses these challenges by training the next generation of researchers to develop a new class of reconfigurable metasurfaces combining simplicity of implementation, multifunctionality, and industrial viability. These metasurfaces will feature unified tunability mechanisms, reducing complexity and energy usage, while incorporating innovative materials for enhanced adaptability, robustness, and endurance. Furthermore, the project will pioneer cost-effective fabrication techniques, ensuring compatibility with large-scale production. The program adopts a multidisciplinary approach, conducting application-driven research in four high-impact domains: communication systems, thermal management, sensing, and imaging. Beyond scientific training, participants will gain comprehensive industry exposure and develop transversal skills, preparing them for diverse career pathways in academia and industry. By tackling these critical technological challenges, MetaTune not only advances fundamental knowledge in physics and engineering but also bridges the gap between laboratory research and industrial implementation. This project paves the way for integrating reconfigurable metasurfaces into practical systems, delivering societal benefits through improved connectivity, sustainability, safety, and innovation.
