Novel electromagnetics for next-gen communications


As 5G is currently being worldwide deployed as the planned successor of 4G, telecommunication leaders are alreadyexploring the next frontier of 6G, the sixth generation of wireless communication technologies. 6G is expected to be much faster and diverse than its predecessors, supporting applications beyond current mobile use scenarios, such as virtual and augmented reality (VR/AR), ubiquitous instant communications, pervasive intelligence, and the Internet of Things (IoT). Such capabilities will be presumably attained by tapping into the millimeter-wave and terahertz range of the electromagnetic spectrum, where absolute bandwidths are massively larger than typical 5G microwave bandwidths.  However, the actual physical principles and technological means to attain the targeted performance and applications are currently a matter of research.

Given the targeted frequency ranges, 6G will be operating in aregime of unprecedently broad signal bandwidth and high radiation directivity. This will require electromagnetic schemesthat extend beyond the mere combination of microwave and optical concepts. Imec and KUL will leverage the novel paradigm of Generalized Space-Time Engineered Modulation (GSTEM) metamaterials [11], or GSTEM for short, to address this challenge. GSTEMs are artificial media formed by the simultaneous modulation in space and in time of a host material. They offer virtually unlimited opportunities to manipulate the spatial and temporal spectra of electromagnetic wave, which leads to abundant novel physics and trailblazing technology.This project will both develop GSTEM systems that may instrumentally contribute to the successful development of 6G.
