Electromagnetic Integrity Engineering™
for Nuclear, Fusion, Research, Medical, and Semiconductor Equipment and Facilities
"Where your troubleshooting ends, and you have exhausted all of your ideas, our work begins."
ELEXANA engineers electromagnetic integrity wherever electrical and electronic performance cannot be left to chance: EMC design and redesign for facilities and products, electromagnetic evaluation, and the forensic resolution of complex EMI problems that conventional methods alone cannot solve.
Our ISO-17025 instrument accredited calibrations are not the same as a supplier's certificate. It states the measurement uncertainty. That is what allows a compliance determination to be made defensibly, with the uncertainty applied and the decision rule stated, rather than a reading compared to a limit and called good.

ELEXANA does not provide legal advice, zoning approval, or FCC certification; we provide electromagnetic measurement, engineering interpretation, and independent technical documentation.
-
Grounding and bonding decide whether a facility's electronics work. They are also the systems least likely to be revisited once concrete is poured, which is why they are worth getting right at design stage and expensive to correct afterward.
Elexana works at both ends. At design stage: ground grid geometry and resistance targets, equipotential and signal reference planes, single-point versus multipoint topology for sensitive instrumentation, bonding of structural steel and reinforcement, lightning protection interfaces, and separation of power and instrumentation returns. Design work is referenced to IEEE 80, IEEE 142, IEEE 1100, IEEE 1050, NFPA 780, NEC Article 250, and, for nuclear facilities, NRC RG 1.180 and EPRI TR-102323.
On existing facilities: soil resistivity by four-pin method, fall-of-potential and clamp-on ground resistance, micro-ohm bonding continuity, insulation resistance, and identification of the ground loops, dissimilar-metal couples, and shared returns that produce noise nobody can locate. Electrostatic work covers floor and footwear resistance, personnel grounding, charge accumulation in material handling, and ESD control programs to ANSI/ESD S20.20.
Verification is where most grounding systems fail. Permanent connections are qualified to IEEE 837, and Elexana specifies measured acceptance criteria at hold points that cannot be revisited later, including pre-pour and pre-fill resistance verification between adjacent connection points. A ground system that was never measured before it was buried is a ground system nobody can vouch for.

Elexana instrumentation is calibrated by ISO/IEC 17025 accredited laboratories, recognized internationally through the ILAC Mutual Recognition Arrangement. An accredited calibration is not the same as a supplier's certificate. It states the measurement uncertainty. That is what allows a compliance determination to be made defensibly, with the uncertainty applied and the decision rule stated, rather than a reading compared to a limit and called good.
-
Calibration certificates are always included, as is complete documentation of instruments, measurement procedures, and applied uncertainty. Another engineer can repeat the measurement and evaluate the result independently. We also conduct third-party review of other firms' reports.
-
We have many gadgets, jigs, and methods we invented for EMI work. Galileo Method, Causal Field Realignment, Field Integrity Coherence Design, & more. We even have a new patent-pending invention coming out soon that will change the way our industry does its work.
-
We have built a portable travel lab ready to deploy anywhere in the USA.
-
We specialize in testing, diagnosing, and resolving complex electromagnetic interference (EMI) and RF/EMF exposure impacting workplaces, facilities, equipment, and product design. We use metrics and tools used by the NSA and DARPA, RF Design Engineers, and Scientists.

ELEXANA - the originators of
ELECTROMAGNETIC INTEGRITY ENGINEERING™
for electrical and electronic systems.
What is Electromagnetic Integrity Engineering™?
Modern facilities are increasingly dependent on sensitive electronics, automation, robotics, high-speed communications, and complex electrical infrastructure.
Yet traditional engineering disciplines rarely consider how electromagnetic interactions influence the reliability and performance of these systems.
ELEXANA developed Electromagnetic Integrity Engineering™ to bridge that gap.
Electromagnetic Integrity Engineering™ is the engineering discipline focused on ensuring the reliable operation of electrical and electronic systems through the evaluation, design, measurement, and control of electromagnetic phenomena, including attenuation, mitigation, control, containment, grounding, bonding, EMI, ESD, power quality, thoughtful EMC design, and related environmental factors.

James J. Finn
Founder and Senior Consultant
Jim leads Elexana's technical work and is on site for the engagements that require it.
He is brought in when a project cannot move forward. Systems fail for reasons nobody can locate, schedules stop, and conventional troubleshooting has already been exhausted. His practice starts by learning the client's system in full, to the working depth of the engineers who designed it, and the diagnosis proceeds from there. When existing methods cannot produce the data a problem requires, he develops the method that will. Several of the resulting test procedures and a patent-pending measurement tool are in use in the practice.
Problems identified outside the original scope get reported and solved. Clients across linear accelerators, driver assistance, autonomous ground vehicles, surgical robotics, industrial automation, semiconductor tooling, and nuclear and fusion facilities have engaged him repeatedly and across widening scope on that basis.
Recent work includes the Valar Atomics Ward 250 reactor, which reached criticality at the Utah San Rafael Energy Lab on June 18, 2026 under Executive Order 14301, the first DOE-authorized advanced reactor built and operated outside the national laboratory system. Jim was on site through the campaign and subsequently wrote the engineering design requirements for the associated 10 CFR Part 70 licensed fuel facility. Other recent work includes remanence prevention for a high-temperature superconducting magnet facility.
Elexana holds no PE stamp and does not seek one. The work is consultation grounded in physics and measurement; the client's engineer of record stamps the design. That separation keeps the analysis independent.

Mobile EMI-EMC Test Lab
Pre-Compliance Testing & Compliance-Failure Analysis
We travel to you, anywhere in the USA, the site where your equipment is malfunctioning, or you can ship it to us.
We provide direct EMI/EMC investigation services, pre-compliance testing, and client-focused collaborative solutions.
If equipment is failing due to EMI, we can determine whether the interference is local or global, or due to equipment susceptibility or immunity design deficiencies, using proprietary test setups and protocols.
This is why we are called on for the most complex EMI issues across America.
Once the root cause or causes are identified, we present your options for resolving the problem(s) causing interference.
