Description The fluidic and shape shifting properties of gallium-based liquid metals have been utilised in reconfiguring and programming microwave devices to generate multiple, adjustable or adaptive functionalities. To integrated with traditional solid state devices, the liquid metals are contained in microfluidic channels. The fabrication processes for microfluidic channels were first established using soft lithography and 3D printing techniques. A number of liquid metal enabled novel devices have been demonstrated. This includes:
(1) A high-performance tunable phase shifter based on a novel via-pad-slot (VPS) structure and liquid-metal enabled tuning mechanism. The phase shifter shows low loss (therefore high efficiency), high phase resolution and low dispersion, surpassing traditional phase shifters. A patent has been submitted based on this work.
(2) A cluster of liquid metal enabled switches, switching filters and switchplexers by exploring the new tuning and programming capabilities offered by liquid metals.
(3) An antenna array with full polarisation reconfigurability between four polarisation states using a liquid metal enabled reconfigurable feed network. The work demonstrated the unique capability of liquid metal in changing the width of microwave transmission lines and a novel functionally-reconfigurable coupler that can transform between a hybrid coupler and a cross over.
(4) A dual-band scanning array using liquid metal enabled reflection-type phase shifters. This is a large complex antenna system that can operate over two frequency bands with beam scanning. A new phase shifter technology was implemented.
Exploitation Route (1) Demonstrated device technologies taken up by other academic researchers. We have already seen an increase in the research activities in the use of liquid metals in high frequency devices.
(2) Patent taken up by industry.
(3) Technology developed in this grant being extended to other areas such as flexible electronics and sensors.
