The 2024 Roadmap on Wireless and Microwave Metasurfaces

Development of microwave metamaterials is at an exciting moment, where the use and design of metamaterials is spreading from the antennas and electromagnetics communities and increasingly being used by communications, control and systems engineers. This is driven by exciting applications such as Reconfigurable Intelligent Surfaces (RIS) and steerable satellite antennas, but presents challenges in terms of knowledge exchange, technology translation and production scale-up. This roadmap brings together contributions from academia, government and industry across the UK to map the state-of-the-art, draw key challenges still to be solved, and set out recommendations for the next steps in fundamental and applied research. This is part of a joint benture by the UK Metamaterials Network and the Institute of Physics to map the whole breadth of research covered by the umbrella term “metamaterials”.
