Nonlinear Stacked Intelligent Surfaces for Wireless Systems
Omran Abbas, Abdullah Zayat, Loıc Markley +1
Stacked intelligent surfaces (SIS) are a promising technology for next-generation wireless systems, offering an opportunity to enhance communication performance with low power cons…
Delay-Augmented Stacked Intelligent Surfaces: Potential, Challenges, and Opportunities
Hibatallah Alwazani, Omran Abbas, Loic Markley +1
Stacked intelligent surfaces (SIS)s have been proposed recently as an enabling technology for Holographic Multiple Input Multiple Output (HMIMO) and Ultra-massive MIMO (umMIMO) tec…
Deep Complex-valued Neural-Network Modeling and Optimization of Stacked Intelligent Surfaces
Abdullah Zayat, Omran Abbas, Loic Markley +1
We propose a complex-valued neural-network (CV-NN) framework to optimally configure stacked intelligent surfaces (SIS) in next-generation multi-antenna systems. Unlike conventional…
A Tunable Reflection Surface with Independently Variable Phase and Slope
Omran Abbas, Anas Chaaban, Loic Markley
A reconfigurable intelligent surface (RIS) is an essential component in the architecture of the next generation of wireless communication systems. An RIS is deployed to provide a c…
Unit Cell Phase-Frequency Profile Optimization in RIS-Assisted Wide-Band OFDM Systems
Omran Abbas, Qurrat-Ul-Ain Nadeem, Loïc Markley +1
The reflection characteristics of a reconfigurable intelligent surface (RIS) depend on the phase response of the constituent unit cells, which is necessarily frequency dependent. T…
