Physically Accurate Differentiable Inverse Rendering for Radio Frequency Digital Twin

ArXi:2603.18026v1 Announce Type: cross Digital twins, virtual simulated replicas of physical scenes, are transforming system design across industries. However, their potential in radio frequency (RF) systems has been limited by the non-differentiable nature of conventional RF simulators. The visibility of propagation paths causes severe discontinuities, and differentiable rendering techniques from computer graphics cannot easily transfer due to point-source antennas and dominant specular reflections.
