Purpose and goal
The project aims to develop sustainable, energy-efficient antenna technologies for the sub-terahertz range, essential for future 6G systems. It focuses on fully metallic designs to maximize efficiency. Advanced manufacturing methods like additive manufacturing, Focused Ion Beam micromachining, and metallized photolithography will be studied.
Expected effects and result
The project will design, fabricate, and experimentally validate at least three high-efficiency FulMet metalenses for the sub-THz range. These results aim to significantly reduce both energy loss and material waste, strongly supporting the idea that sustainable, low-impact manufacturing is fully compatible with the demands of high-frequency antenna technologies. This research represents a step forward in enabling advanced wireless communications for future smart and interconnected societies.
Planned approach and implementation
The approach combines the design, simulation, fabrication, and testing of FulMet metalenses using additive manufacturing (AM), Focused Ion Beam (FIB), and metallized photolithography (PhLi). The training will take place at KTH ensuring comprehensive knowledge transfer, technical innovation, and experimental validation across diverse environments.
