This project aims to study liquid-based techniques for reconfigurable antennas and reflectors (RARs) in the sub-Terahertz (sub-THz) band. This is to overcome the severe path-loss and limited coverage intrinsic to sub-THz signals to enable extremely high-speed communications via the vastly available bandwidth. The dynamic reconfiguration of narrow beams towards the intended direction(s) by RARs is expected to extend the signal coverage significantly while reducing costs/energy in place of base stations. The liquid-based reconfiguration technique offers an extensive structural reshaping capability, and such feature is not available in any other current feasible reconfiguration methods for sub-THz RARs. This solution is expected to be resource-efficient to catalyse the use of the sub-THz band for 6G communications, accelerating the digitalization of economy, society, and sustainability.
