Abstract:
Free space optical (FSO) network represents an efficient means to deal with the “last-mile” problem in wireless networks. In these systems, data transmission takes place between an optical transmitter and a receiver located, for example, on high buildings, separated by several hundred meters. Relaying is also an efficient technique for handling the multipath fading problem in wireless networks. A mixture of relay and FSO networks has been widely considered to increase the coverage distance of FSO networks, and to multiplex multiple radio frequency (RF) users into one FSO link. Reconfigurable intelligent surfaces (RISs) represent a new low-cost and less complicated solution to realize wireless communication with high energy/spectrum efficiencies. A RIS is an artificial surface, made of electromagnetic material, that is capable of customizing the propagation of the radio waves impinging upon it. It could be implemented at either the source itself or as a replacement to relay. In this talk, we investigate and compare these two scenarios of RIS in a mixed RF/FSO relay network context.
Bio:
Anas M. Salhab was born in Hebron, Palestine. He received the Ph.D. degree in Electrical Engineering from King Fahd University of Petroleum & Minerals (KFUPM) in 2013. He served as an Assistant Director of Science & Technology Unit in the Deanship of Scientific Research in KFUPM for 7 years before joining in 2021 the Electrical Engineering Department in KFUPM where he is now a Visiting Assistant Professor of Electrical Engineering. Dr. Salhab is a Senior Member of the IEEE. His current research areas of research span various topics in wireless communications, including free space optical communications, reconfigurable intelligent surfaces, underwater wireless optical communications, mixed wireless communication systems, and unmanned aerial vehicles.
Faculty, researchers and graduate students are invited to attend (up to 40).
