From Aircraft to Arrays: Breaking Through the Scale Barrier in RF Simulation | Dr. Masha Petrova

Watch Dr. Masha Petrova, CEO of Nullspace, as she presents "From Aircraft to Arrays: Breaking Through the Scale Barrier in RF Simulation." This presentation was made in the HUB at the 2026 AIAA SciTech Forum in Orlando, Florida.

Traditional EM simulation tools struggle with electrically large structures—problems spanning dozens to hundreds of wavelengths encounter severe memory and computation time constraints. Nullspace was purpose-built to eliminate these barriers. This presentation demonstrates our capabilities through two critical applications: large phased arrays and large-scale RCS analysis—problems that historically required HPC clusters, now achievable on engineering workstations. Beyond solver performance, engineers typically spend 20-40% of simulation time on CAD cleanup. Discover how Nullspace's newest release features physics-aware CAD defeaturing that automatically removes electromagnetically irrelevant mechanical details while preserving critical RF elements, reducing prep time by up to 90%. Combined with Fast Adaptive Frequency Sweeps, this integrated workflow enables true rapid iteration on complex designs—exploration that's theoretically possible but practically prohibitive with legacy EM tools.
