Fundamentals of EMC Design: Our Products Are Trying To Help Us
We often design electronic products only to find that when we test them for electromagnetic compatibility (EMC), their emissions and/or immunity are not as good as we need them to be.
Usually, at this time, we feel as if we arefighting against the laws of physics to containthe conducted and radiated emissions,or to reduce susceptibility.
But in fact the laws of physics – Maxwell’sEquations – are causing our designto have the best emissions and immunitythat the physical structure allows. We mightsay that our product is doing the very bestit can to reduce its emissions and improveits immunity!

EMC Standards is a world-leading resource for all things EMC and EMI related. Our website is packed full of both free and paid-for content, including:
- Online quiz
- Webinars
- Training quiz
- And much more!
Electromagnetic Engineering (EMgineering) is the basis for proven good design practices for signal integrity (SI), power integrity (PI), and the control of EMI emissions and immunity (EMC).
Our aim is to help people learn how to more quickly and cost-effectively design and manufacture electronic equipment (products, systems, installations, etc.) to meet functional (i.e. SI/PI) specifications and conform to EMC standards, directives and other requirements.
Such equipment should benefit from reduced warranty costs and financial risks, whilst improving uptime, competitiveness and profitability.
We also cover basic good electrical safety engineering; and the Risk Management of Electromagnetic Disturbances / EMI, whether for Functional Safety or other types of risk.
