Circuit Modelling of Reflecting Intelligent Surfaces
2021 IEEE 22nd International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2021We present an accurate and simple analytical model for the computation of the reflection coefficient amplitude and phase of Reflecting Intelligent Surfaces (RIS). The proposed approach takes into account mutual coupling among cells, the effect of incidence angle and polarization of impinging electro-magnetic waves.

Double Intelligent Reflecting Surface for Secure Transmission With Inter-Surface Signal Reflection
IEEE Transactions on Vehicular Technology, 2021In this correspondence, we use double intelligent reflecting surface (IRS) assisted design to enhance the secrecy performance of wireless transmission. Different from the existing studies in the literature, the inter-surface signal reflection is considered in this work, which makes the formulated secrecy rate (SR) optimization problem difficult to ...

Intelligent Reflecting Surfaces Enhanced Federated Learning
2020 IEEE Globecom Workshops (GC Wkshps, 2020This paper investigates the problem of model aggregation for the federated learning aided by multiple intelligent reflecting surfaces (IRSs). Since the local parameters are transmitted over wireless channels, the undesirable propagation error will inevitably deteriorate the performance of global aggregation.
