Stacked Intelligent Metasurfaces Enabled Joint Signal Processing and Communication in the Wave Domain

We propose a new wave-based computing architecture called stacked intelligent metasurfaces (SIM) to enable joint signal processing and communication in electro-magnetic (EM) domain. An SIM is fabricated by stacking an array of programmable metasurface layers, where each layer consists of many low-cost passive meta-atoms that can individually manipulate EM waves. By appropriately configuring the passive meta-atoms, an SIM can automatically accomplish advanced computation tasks as the EM wave propagates through it, while reducing both the energy consumption and processing delay. In this talk, we will illustrate the application of SIM in multiple-input multiple-output (MIMO) and multi-user MIMO wireless communications.
