Abstract
This talk covers two research thrusts exploring the use of 3D printing and gallium-based liquid metals for microwave and mm-wave devices and antennas. The first part examines the challenges and opportunities of 3D printing (also known as additive manufacturing) for microwave hardware, with a focus on space applications. I will then use several examples to demonstrate the capability of ‘high-precision’ 3D printing in producing mm-wave and even sub-terahertz waveguide antennas, feeders and filters operating up to 500 GHz.
The second part of the talk focuses on our recent work on liquid-metal-enabled reconfigurable circuits and antennas. Representative devices will be presented, including a high-performance dispersion-less phase shifter, a quad-polarization-reconfigurable array, and a reconfigurable metasurface.
