Surface Wave Technique Enabled RIS Applications

Increasing demands on high-performance platforms in the sixth generation (6G) of mobile communications raise research focus on new transducers. Recently, reconfigurable Intelligent Surfaces (RIS) have been proposed to address both the coverage and power issues. However, it may not be sufficient to solely rely on the manipulated reflections on RIS in the cases of high free-space path loss and blind spots in urban areas. To bridge such a gap, we propose a novel surface wave technique to enable a new communication surface to tackle the coverage and power concerns.
