01 — EMC Engineering
Tools built on the test floor.
More than twenty years of EMC across commercial, aerospace, defence and space: emissions and susceptibility, receiver setup, standards interpretation, measurement uncertainty, and fault-finding under programme pressure. These are the calculators and explainers that career produced.
Calculators & explainers
RF Unit Converter
dBµV, dBmV, dBV, voltage, current and power — converted around a 50 Ω default.
Open → 02Field Strength Calculator
One value in, every field unit out — plus the far-field link between power, gain, distance and field.
Open → 03Standards Placement Checks
RE103 separation, frequency-aware RS103 position planning, and a separate Fraunhofer check for DO-160 §20 planning.
Open → 04MIL-STD-461G Receiver Examples
Four individual plots corresponding to Appendix Figures A-5 through A-8: 10 s and 300 s scans, then 15 ms and 1 s FFT records.
Open → 05EMI Receiver Bandwidth
Resolution bandwidth, impulse bandwidth and detector behaviour for EMC receiver measurements.
Open → 06EUT Antenna Positions
Practical antenna centre positions for illuminating a rectangular EUT with a circular footprint.
Open → 07Grounding & Bonding Explained
Star vs mesh earthing, common-impedance coupling and parallel earthing conductors — the whiteboard version.
Open → 08Bond Strap Impedance
Why a 2.5 mΩ bond can present tens of ohms at RF — with a live impedance-vs-frequency chart.
Open → 09Skin Depth Calculator
How deep RF current penetrates copper, steel and platings — with a to-scale cross-section.
Open →The point of all of it
A good measurement is one you can defend — the number is just the last step.
Where it comes from
The road through EMC.
Airbus came first: table-top EMC testing of satellite and ground station equipment to MIL-STD-based internal plans. Then eleven years at Element, where I learned commercial EMC test work and the complete range of tests around it, at high throughput — the environment where you learn what standards really mean by getting them wrong under supervision, and climb from technician to laboratory manager while you do. Back to Airbus with a more holistic approach, testing and analysing spacecraft and payload hardware to MIL-STD-461 and ESA requirements. Then facility definition at Mangata as Director of Spacecraft Test, aerospace and defence business management at Eurofins, and now Lead EMC Engineer at Leonardo, supporting radar and combat air programmes.
Every tool in this section exists because a real job needed it — to make a calculation faster, a setup decision clearer, or a teaching point stick.
