End-to-End Learning With EM-Aware Differentiable-Ready Discrete-Phase RIS for MIMO–OFDM via Ray Tracing

Most learning-based reconfigurable intelligent surface (RIS) designs assume continuous control or closed-box channel models, limiting physically grounded end-to-end (E2E) training and neglecting practical 1-bit hardware constraints. We propose a physics-informed framework for RIS-assisted MIMO–OFDM that embeds an optic...
