Mitigation/Shielding

FMS achieves effective EMF/EMI mitigation through creative and restrained use of mitigation technologies, many of which are low-tech and inexpensive.  FMS has become the leader in cost-effective, 100% compliant EMF/EMI solutions.  FMS holds US patents for shielding magnetic fields, and has pioneered innovations in EMI process and materials.  FMS was the first in the United States to introduce low-cost, high performance aluminum shielding to mitigate magnetic fields.

Increasingly, passive magnetic shielding is the preferred option to reduce Geo-Magnetic, Quasi-DC, and AC (power frequency) magnetic field levels to mitigate equipment interference (EMI) or possible health risks (EMF).  Passive magnetic shielding can include shielding either the “Source” or the “Victim” affected area(s), and the mitigation strategies in terms of material selection, thickness, orientation, etc. can vary greatly.

FMS provides comprehensive guaranteed EMF/EMI mitigation and shielding design services as well as full Turn-Key installation services.  FMS also provides design and mitigation installation services for radio frequency (RF) fields (e.g. MRI, EEG, etc.).

Active Compensation Systems (ACS) are another choice when mitigation is necessary.  FMS works closely with several ACS vendors throughout the globe and is able to provide the client with the best choices the industry can provide.

In the ever-changing, sophisticated technology used in a variety of many disciplines of scientific research, the required ambient electromagnetic environments needed to house tools and equipment are becoming increasingly EMI sensitive, and therefore, are becoming routinely dependent on a combination of both “passive” and “active” technologies working in concert to achieve the necessary environmental requirements.
