What Electro Magnetic Applications does

Electro Magnetic Applications, Inc. (EMA) is a privately held engineering firm founded in 1981 and headquartered in Lakewood, Colorado, with an additional test facility (the SERE Laboratory) in Pittsfield, Massachusetts. The company develops and validates electromagnetic (EM) and plasma simulation solvers, primarily the EMA3D finite-difference time-domain (FDTD) platform, which now ships commercially as Ansys EMC Plus and Ansys Charge Plus following the acquisition of Ansys by Synopsys. Its core technology combines Particle-in-Cell (PIC), finite-element electromagnetic, fluid/CFD, and chemical reaction solvers with multi-fidelity coupling to TCAD Sentaurus for semiconductor plasma simulation, plus GPU acceleration via an NVIDIA partnership. EMA holds a pending international patent (PCT/US25/51404) for a 3D CAD-integrated simulation platform unifying these multiphysics solvers.

EMA serves aerospace and defense, advanced air mobility/eVTOL, semiconductor manufacturing, automotive, rail/transportation, and spacecraft/satellite customers. Its primary use cases are lightning direct/indirect effects, HIRF certification, fuel-system 25.981 compliance, EMI/EMC, electrostatic discharge (ESD), spacecraft charging, and radiation effects. Named customers and program references include Saab (Gripen), Bombardier (CSeries), Mitsubishi Regional Jet, Lockheed Martin (Orion), NASA (Artemis spacesuits), Bell Helicopter, Sierra Nevada (Dream Chaser), Orbital Sciences, BETA Technologies, and CSX. The firm supports FAA and EASA certification pathways, with validation heritage cited in SAE ARP5415 and across DO-160, MIL-STD-461/464, ARP5415/5416/5583, and IEC 62153-4-3 standards.

The business model combines three revenue streams: (1) simulation software licensing distributed via the Ansys/Synopsys channel as Ansys EMC Plus, Ansys Charge Plus, and Ansys STK Shield Plus; (2) professional engineering consulting for E3 design, analysis, and certification programs; and (3) physical testing and measurement services, including full aircraft HIRF/lightning testing, DO-160 and MIL-STD compliance, transfer impedance measurement, and SERE Laboratory testing for spacecraft charging and radiation effects. Go-to-market is enterprise field sales combined with technical content marketing (EMA Expo, webinars, training videos) and free 30-60 day software demos. Customers cite up to 30% reduction in time-to-market by simulating early in the design cycle to reduce physical testing.
