Electro Magnetic Applications, Inc (EMA). was incorporated in New Mexico in 1977. The President is Dr. Rodney A. Perala, a recognized authority in electromagnetic effects. Corporate headquarters are located in Denver, Colorado.

In its early years, EMA focused on the effects of nuclear weapon induced ionizing and non ionizing (Nuclear Electromagnetic Pulse) radiation on a wide variety of military and civilian systems, as well as lightning effects upon systems. These efforts  included the analysis, hardening  and testing of systems such as the Space Shuttle, military and civilian aircraft, various missiles (e.g., Minuteman, Peacekeeper, Trident, Pershing, and many smaller systems), ships, tanks, armored personnel carriers, strategic and mobile  Command, Control and Communication (C3) facilities. EMA made essential contributions to the understanding and prevention of the ignition of solid rocket propellants due to electrostatic fields induced during handling. These activities were carried out both in the USA and in Western Europe; additional global involvement included the participation on international standards and safety committees, such as the SAE AE4L Lightning Committee, the SAE AE4R High Intensity Radiated Fields (HIRF) Committee, and others.
