Graphene-based terahertz reconfigurable printed ridge gap waveguide structure

“…Mohamed Mamdouh M. Ali 1* , Shoukry I. Shams 2 , Mahmoud Elsaadany 3 , Ghyslain Gagnon 3 & Ke Wu 4 Graphene-based microwave devices have enabled reconfigurability, thus paving the way to the realization of flexible wireless terahertz systems with featured performances. Despite great progress in the development of graphene-based terahertz devices in the literature, high insertion loss and wide tunable range are still significant challenges at such high frequencies.…”

“…Reconfigurable systems can be constructed through deploying sub-systems having the ability to reversibly change their functionality under some controlling process. One of the major revolutions of reconfigurability in electronics is the field-programmable gate array (FPGA), which has a powerful impact on digital design methodologies alongside wireless systems 2,3 . In a related context, few trials are initiated to develop reconfigurable microwave components providing an additional level of functionality for wireless systems.…”
