Full-wave, high-fidelity simulation for real-world applications. Validated on 15+ years of production hardware for the defense industry.
A fundamentally different architecture for fundamentally harder problems
Where legacy solvers run out of memory and force engineers to simplify models, Nullspace EM can simulate the entire system. Our proprietary adaptive matrix compression algorithm allows users to run electrically large problems on their standard engineering workstations in hours instead of days without any loss of accuracy.
Full-wave, 3D electromagnetic simulations
Nullspace rigorously solves Maxwell's equations - the same full-wave formulation whether you're modeling a single antenna element or a large-scale phased array integrated onto a platform. As the problem scales, there are no asymptotic approximations. Nullspace provides high fidelity solutions to full system-scale problems.
Defense-validated, production-proven,
15+ years
Nullspace's solver technology was developed in stealth, at an established U.S. defense contractor specializing in sophisticated cutting-edge RF systems, before spinning off as an independent company in 2023. Built from the start to run in secure environments, it delivers results that serve as a source of truth for real-world defense and aerospace systems.
Purpose-built solvers for the hardest problems in RF and quantum computing
Built for RF
Full-wave 3D electromagnetic simulation software for design and analysis of antennas, radars and platform-level RF analysis.
Built for Quantum
The world’s only commercial software purpose-built for simulation of extremely large ion trap design and analysis.
Built for Large Problems: Scaling a Phased Array
The same 15.5 GHz phased array was run on Nullspace EM and on a well-known legacy tool, scaled from a single element up to a 32×32 array of 1,024 elements. The legacy tool stopped completing runs above 8×8.
Nullspace EM completed every case in the benchmark.
Key takeaways
CST exhausted memory above 8×8 and failed to complete the 16×16 and 32×32 cases on every machine tested, including a 256 GB workstation.
Nullspace EM completed the full series, finishing the 1,024-element array in 5.7 hours at 170 GB, within reach of a single workstation.
At every size where both tools finished, Nullspace was 3–23× faster and used roughly an order of magnitude less memory.
Set up simulations in plain English
Describe the analysis you want and the AI agent builds the model, runs it, and post-processes the results via the Python API. You review and adjust instead of clicking through menus.
Capture your team’s expertise
Encode how your experts configure and evaluate problems in Python. Colleagues, pipelines, and AI agents run it the same way every time.
Cover the full design space,
not just a few points
Parametric sweeps, optimizations, and uncertainty analyses run as ordinary scripts, becoming standard steps in your workflow instead of one-off efforts per program.
Nullspace was developed in stealth at an established U.S. defense contractor for 15+ years, and verified against real program requirements and validated on antennas, radars, and RF systems physically built and delivered to defense customers. Although that work isn't publicly releasable, it's the foundation our software was proven on long before Nullspace became a separate company in 2023 and launched Nullspace EM and ES as commercial software.
CMMC Level 2 Compliant.
Operable in air-gapped environments.
Currently deployed on multiple classified information systems.

"We attempted to model a full phased array with our existing software solution. It was estimated to take over 30 days to complete. We couldn't tolerate a hit to our schedule like that. With Nullspace, we completed the full analysis in less than 1 day."
— Senior RF Engineer, Defense Contractor
“Using Nullspace EM, our model-to-measurement agreement was so good that we were able to make significant modifications to the design without the need to do any prototyping.”
— Branch Head, U.S. Defense Research Lab
"A test model ran in 6 hours on Nullspace EM. The same problem, same mesh, took 16.5 hours on a competing commercial tool."
— Senior Engineer, Federal U.S. Laboratory
