VitaTech Electromagnetics provides specialized full-spectrum
(0 Hz - 300 GHz) professional electric and magnetic fields (EMF) and
electromagnetic compatibility (EMC)
engineering consultation services in the areas of concept development and
requirements analysis. VitaTech prepares concept studies, requirements
definition/analysis,
and statement-of-work (SOW) of EMF and EMC engineering projects by specifying
the following:
-
EMF site survey protocols performed on device, building or site
(future or existing) to measure/record electric and magnetic fields.
The EMF site survey protocol includes the type of EMF source to be
measured (electric or magnetic static DC, AC ELF, VLF/LF and RF fields),
methodology of the data collection (spot, mapped/contour and timed),
recommended instrument/probe (coil, fluxgate and hall-effect magnetometers,
etc.) and graphical methods to present EMF data.
-
EMF simulations of electrical systems including transmission/distribution
lines, transformers, switchgears, busways, risers, conduits, panels,
subways/trains.
-
RF modeling of antenna patterns, electric field strength profiles
of marine, mobile, pagers/cellular/PCS, AM/FM, UHF/VHF, microwave & radar
antennas.
-
EMC measurement protocols & assessments (to be MIL-STD & NSA
compliant)
-
Acceptable electromagnetic and radiofrequency interference (EMI/RFI)
threshold levels to minimize the potential impact on electronic equipment,
telemetry & diagnostic systems, communication systems, computers & CRT
monitors, servers and IT networks, scientific research instruments
as defined by selected standards.
-
Recommended EMF human risk assessment for government/military personnel,
contractors, and visitors from EMF emission sources based upon various
industry, national and international standards: ACGHI, NCRP, IRPA/INIRC,
OSHA, WHO, and the FCC OET Bulletin 65 Evaluating Compliance with
FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic
Fields.
VitaTech provides evaluation of alternative technical approaches and
associated costs for the development of EMF and EMC engineering services
that minimize potential EMI, RFI and EMC problems in devices, new/existing
buildings and large sites, including:
-
Specifications with estimated costs for comprehensive EMF site surveys
and measurements, shielding performance testing (IEEE-STD-299), EMI/RFI
assessments, EMC standards/policies (MIL-STD & NSA compliant)
and EMF human exposure standards, for the following EMF sources:
-
Static DC EMF sources (geomagnetic, subways, MRIs, NMRs, etc.)
-
AC ELF (extremely low frequency) EMF sources (power lines & equipment)
-
VLF (very low frequency) and LF (low frequency) EMF sources
(CRT's)
-
RF (radiofrequency) EMF sources (mobile, marine, UHF/VHF, cell/PCS,
etc.)
-
PQ (power quality) sources (harmonics, voltage/current surges,
etc.)
-
EMP (electromagnetic pulse) & HEMP (high-altitude electromagnetic
pulse)
-
Specifications with estimated costs for recommended electric & magnetic
fields (EMFs), RF, EMI/RFI, EMP/HEMP and EMC remediation objectives:
-
Magnetic, Electric, RF & SCIF, TEMPEST, EMP/HEMP Shielding
Systems
-
Active/Passive Cancellation Systems, EMI/RFI & Harmonic/Sequence
Filters
-
IEEE, N.E.C. & N.E.S.C. applied electrical standards & corrective
measures
