SUMMARY:Ali Al Qaraghuli's PhD Proposal Review
DESCRIPTION:“Terahertz Communication for Space Systems” \nAbstract: \nWith the ultimate vision of ubiquitous egalitarian worldwide coverage driven by the rapid proliferation of high-speed satellite networks\, private companies are launching satellites into orbit at unprecedented rates. The main goal of such networks enabled by dense constellations in space is to build a more robust telecommunications infrastructure and provide worldwide internet access to users on Earth. Similarly\, small satellites are included in the vision of non-terrestrial networks (NTN) for 6G networks which promise for more connectivity on Earth. The significant projected traffic in the orbital uplink\, downlink\, and crosslink communication will demand more spectrum to suit more users and satisfy the need for higher data rates. Similarly\, the push towards using smaller satellites in the form of CubeSats will require the hardware to be more compact than ever. This introduces the terahertz band (0.1-10THz) as a candidate technology to satisfy both large bandwidth and device compactness requirements due to the smaller wavelength of terahertz signals. These two advantages\, however\, come at the cost of high propagation losses and impose the use of very high-gain directional antennas\, leading to limitations in constellation network design. This proposal evaluates terahertz communication in space in contrast to competitor technologies such as microwaves and free-space optical communication\, and establishes the feasibility of terahertz networks in space. Next\, the areas of research and innovation required to realize terahertz space communication systems are identified and explored. Finally\, advancements in those areas are presented\, and the next steps are identified to transform terahertz space communication systems into reality. \n  \nCommittee: \nProf. Josep Jornet (advisor) \nProf. Tommaso Melodia \nProf. Kaushik Chowdhury
