PhD Thesis: Differentiable Ray Tracing for Radio Propagation Modeling
jeertmans · reddit · 2026-07-07
The author shares their PhD thesis, "Differentiable Ray Tracing for Radio Propagation Modeling," written in a textbook style across three self-contained parts: physical foundations (like electromagnetism and geometric optics), algorithmic cores (including GPU-accelerated path tracing and discontinuity smoothing), and applications (such as channel modeling).
The research integrates automatic differentiation frameworks like JAX into the ray tracing pipeline. This allows for exact gradient computation in complex physical environments, serving inverse problems and ML model training in next-generation wireless design.
