Simulating billions of electromagnetic ray paths per second across dense urban geometry using NVIDIA OptiX and CUDA RT cores.
ISACSim leverages hardware ray-tracing RT cores to evaluate ray-triangle intersections at scale, simulating up to 10 bounces of reflection, transmission, and edge diffraction in high-density smart cities.
At each reflection surface, physical optics calculates induced surface current distributions, integrating scattered electric and magnetic field vectors to deliver exact phase, polarization, and delay profiles.
