Electro Magnetic Applications, Inc (EMA). was incorporated in New Mexico in 1977. The President is Dr. Tim McDonald, 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.

In recent years, EMA has expanded its focus to commercial applications of electromagnetics. In the aerospace industry, these have included a variety of aircraft EME (Electromagnetic Effects) certification projects with activities ranging from full-size aircraft coupling analyses to the calculation of voltages and currents induced at the board level in avionics subsystems. The EM concerns of these projects included lightning, HIRF and EMI/EMC. For ground based systems, lightning protection and mitigation of power line induction effects for railroad signal and communications systems have been areas of significant activity. EMA’s experience in EM analysis has also been made available on a wider basis through the development and sales of powerful, user-friendly EM simulation software and a wider range of consultancy on electromagnetic R&D matters.
