EMF Assessment Surveys
The first step in an effective EMF/EMI Assessment is the ability to identify, document, record, and analyze the existing electromagnetic environment (e.g. Geo-Magnetic, Quasi-DC, AC ELF, and RF field levels) at the site(s) of concern. This is routinely accomplished by conducting a broadband EMF/EMI Survey.
FMS offers full spectrum (0Hz – 3GHz and higher if required) comprehensive site analysis surveys which can be tailored to the client’s specific needs or requirements. The surveys are performed by highly experienced engineering staff using specialized and NIST traceable test equipment.
Utilizing data provided by the results of the site analysis, FMS compares the documented EMF levels to either client-established or equipment EMI/EMC standards to determine if EMF levels exceed EMI/EMC threshold limits. In the absence of specific guidance, FMS relies on published international EMI/EMC standards.
If the predicted EMF environment exceeds a specific EMI/EMC specification, an EMI threat risk will likely exist. For each area determined to be at EMI threat risk, FMS provides recommendations, as appropriate, to mitigate the EMI threat risk to below recommended or established industry EMI/EMC standards.

S provides guidance on “Determining EMI Threat Risk” and the critical decision of a “target” residual field strength specification for mitigation recommendations. FMS provides specific mitigation plans that achieve the client’s “target objectives” along with their associated cost and construction schedule impact.
Recent Projects
FMS as the EMF/EMI Consultant designed and installed the passive and active mitigation systems for this newly established interdisciplinary organization under the Office of Research of the University of California Irvine (UCI) to house state of the art electron-microscope labs (4 imaging cells). The project required analysis of interference potential of all internal and external emission sources, which included vehicle and facility elevators (DC), broadband electrical system (AC) sources, etc.
FMS was engaged as the project’s EMI Consultant by the project architect (Wilson Architects) to conduct an electromagnetic field (EMF) analysis in an existing laboratory (shell space) located in the basement level of the Harvard CNS facility.
Seattle Children’s Research Institute is currently in the construction phase of ”Building Cure”, a 540,000 square foot research building, which will be dedicated to developing therapies for children with diseases such as Cancer, Type 1 Diabetes and Sickle Cell Anemia.
FMS was engaged to conduct a thorough assessment of the building’s design for EMI interference threat concerns to sensitive research equipment. A document review and extensive 3-Dimension computer simulation studies were conducted to evaluate EMF emissions from the building’s electrical distribution, mechanical and other systems.
Over its 20 years, FMS has successfully completed hundreds of EMI projects which included a diverse range of consulting and mitigation services.
