ELEXANA
when electrical and electronic
performance cannot be left to chance.
—> electromagnetic compatibility design and redesign for facilities and products, electromagnetic evaluation, and the forensic resolution of complex EMI problems conventional methods alone cannot solve.
Our ISO/IEC-17025 instrument accredited-certified 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.
NRC RG 1.180, EPRI TR-102323, IEC 60601-1-2, IEEE 644-2019, C95.1-2019, MIL-STD-461.
Where your
troubleshooting ends,
our work begins.
We identify the problem
and design the solution.
Critical equipment experiences intermittent failures that no one can explain.
Control systems, sensors, or instrumentation produce erratic measurements.
Interference is disrupting sensitive equipment or critical operations.
A product is failing EMI/EMC compliance testing.
Difficult grounding, bonding, or shielding problems persist.
A worker or visitor has an implanted medical device, and the facility must ensure electromagnetic safety.
Clients contact ELEXANA when:
Engineering solutions for the world's
most difficult electromagnetic problems.
What Differentiates
ELEXANA
-
Directed by our Chief of Measurements: a Ph.D, E.E, Electromagnetic Engineer with 11-years of professional experience.
-
We are experienced with EMI testing, troubleshooting, drop function resolution, module and facility design of nuclear reactors and their facilities.
-
Whether we work in the OEM facility or where the equipment is in operation, our experience spans nationwide from implanted wearables to MRI, new patents and patent-pending inventions, from medical research labs to new build hospitals and renovation consultation for low EMI, vaccines to surgical robotics.
-
We have experience in testing EMF and EMI in clean rooms for semiconductors and sensitive research equipment, solving EMI issues affecting equipment malfunction, and testing and resolving facility electrical
issues.
-
Coherence protocols for Intelligent Systems, EMI/EMC advanced engineering. Not only have we solved many robotics EMI issues, that included redesigns, we have several patent-pending inventions to take AI and robotics into the new millennium.
-
Where many failed, ELEXANA succeeded; from the ADAS to the KUKA AGVs to the Medical Robotics, and more. We will get it done.
-
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.
-
Here is another area where we stand out among the competition. Our engineering decisions and recommendations are made strictly by their technical merit. We do not push any of our patented mitigation shielding products on clients, nor have any agenda other than to serve you with integrity. To ensure your trust and confidence in us, we strive to be vigilant about avoiding any conflicts of interest. We do not sell mitigation products, manufacture products, nor receive commissions on products we recommend. Other consultants may charge less than us but rely on backdoor ways of increasing their revenue. That’s not us. We work for your interests only.
-
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 serve you with a team-first orientation, putting your needs before ours to find answers that best serve your goals. We test for solutions and provide the Pros versus the Cons for all options.
-
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 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.
-
We are selective about media opportunities and welcome conversations focused on electromagnetic innovation, infrastructure reliability, and positive technology development.

Leadership
James Finn & Dr. Anastasiia Rozhkova — “The Sherlock Holmes and Dr. Watson of EMI Investigations.”
“They work as a focused investigative team: deep diagnostic analysis paired with exacting field support.”
James 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.
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.

Anastasiia Rozhkova, PhD, EE
Electromagnetic Engineer
Dr. Rozhkova holds a PhD in Electrical and Computer Engineering from the University of Illinois Chicago, with doctoral research in electromagnetic scattering and antenna design. She has authored more than ten peer-reviewed publications and taught electromagnetics and EMC laboratory courses.
At Elexana she directs measurement methodology: instrument selection, calibration traceability, uncertainty budgets, and the measurement procedures documented in every report the firm issues. She also leads the firm's computational electromagnetic modeling in HFSS, COMSOL, and FEKO, which allows field behavior to be predicted at design stage rather than diagnosed after commissioning.
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.
