    Motivation and Background<\/strong><\/h4>\n

    The recent research results confirm that the effective deployment of Reconfigurable Intelligent Surfaces (RISs) as controllable reflection surfaces (as well transmission and reception\/sensing) can enhance network coverage for a wide range of frequencies, creating various opportunities for emerging applications, such as localization, sensing, energy efficiency, secrecy, and reduced electromagnetic-field exposure. The RISs can be designed as self-configuring parts of a wireless network infrastructure, adjusting their electromagnetic characteristics in response to dynamic traffic demands and actual propagation characteristics. Besides the research activities world-wide considering various aspects of applications of the RIS technology in frequencies ranging from sub-6GHz to THz, related research is also being conducted in public European projects, such as in the RISE-6G, METAWIRELESS, ARIADNE, TERRAMETA projects, as well as some others from the 5G PPP arena. The purpose of this workshop is to present and discuss the latest research achievements in Europe, as produced by the ongoing projects RISE-6G, METAWIRELESS, ARIADNE, TERRAMETA, and identify future scientific directions and challenges. In particular, the workshop will include presentations (submitted either as extended abstracts or full papers) from these four (4) ongoing projects in RIS modelling and simulators, hardware designs and demos, network integration and RIS optimization algorithms, as well as on future research challenges.<\/p>\n

    Structure<\/strong><\/h4>\n

    The proposed full-day workshop consists of four (4) conference time slots dedicated to presenting and discussing key technical findings of the four (4) ongoing projects on RISs. The workshop will conclude its content with a panel comprising the project\u2019s technical managers that will the lessons learnt, the open challenges, and the road ahead with the RIS technology in 6G networks from sub-6GHz to THz frequencies.<\/p>\n
