Circuit Modelling of Reflecting Intelligent Surfaces
We 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.

Wireless Network Coding With Intelligent Reflecting Surfaces [PDF]
Conventional wireless techniques are becoming inadequate for beyond fifth-generation (5G) networks due to latency and bandwidth considerations. To improve the error performance and throughput of wireless communication systems, we propose physical layer network coding (PNC) in an intelligent reflecting surface (IRS)-assisted environment.

Intelligent Reflecting Surfaces Enhanced Federated Learning
This 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.

Intelligent Reflecting Surfaces for Compute-and-Forward [PDF]
Compute-and-forward is a promising strategy to tackle interference and obtain high rates between the transmitting users in a wireless network. However, the quality of the wireless channels between the users substantially limits the achievable computation rate in such systems. In this paper, we introduce the idea of using intelligent reflecting surfaces
