Increasingly, the intersection of urban planning/mass transit, high-density research environments, and energy-efficient building designs and the emerging next generation of research tools is pushing the limits of standard low-EMI approaches in facilities. FMS represents the next-generation of EMI field management – with innovative approaches and new technologies that address this intersection.
Rail, light rail, subways, bus, airports can affect localized medical, scientific, research facilities, and communication systems. For example, electric powered rail trains may cause interference with flight operations and navigational aid systems due to radio-frequency (RFI) and electromagnetic interference (EMI) emissions from the trains and the associated overhead contact systems (OCS). FMS conducts environmental impact studies and compliance analysis studies coordinated with city/county municipalities, state, and federal agencies.
RAIL, LIGHT RAIL, SUBWAYS:
Operation of light rail or subway systems produce transient magnetic fields that perturb the static background magnetic field (which is primarily the geomagnetic field). There are two components to the magnetic field impact from the light rail system:
Both of these components combine to produce changes in the ambient magnetic field environment with characteristic time-scales typically ranging from a fraction of a second to tens of seconds. The magnitudes of these magnetic field changes are generally strongest near the alignment and decrease moving away from the tracks. Such magnetic field changes can interfere with the operation of sensitive instruments and measurement systems used in research in the physical, biological and health sciences.

Transportation facilities can be high intensity, high density RF environments. Airports utilize radar, landing systems, security systems and communication systems which rely on wireless systems.
Passports are being issued with RFID chips in many countries. RF safety – keeping people safe and keeping devices and networks operational is an integral component of the planning and design process.
Specialized research facilities at the University of Chicago includes the Chicago Instrument for Laser Ionization where leading cosmochemistry is conducted, including
The University of Minnesota NMR Center is a 14,000 GSF facility which houses several 900 MHz, 850 MHz, and 700 MHz and smaller shielded and unshielded magnets.
Over its 20 years, FMS has successfully completed hundreds of EMI projects which included a diverse range of consulting and mitigation services.
