A free reference for engineers who work with EMC. We've distilled the most important theoretical foundations into sixteen topics — from decibel basics to shielding and grounding. Suggestions or questions are welcome at info@academyofemc.com.
1
Decibel
The logarithmic unit used throughout EMC to express signal levels gains and losses.
4
RF Parameters
Key RF parameters including impedance reflection and S-parameters explained for EMC engineers.
7
Antennas
How antennas radiate and receive electromagnetic energy — essential for understanding emissions and immunity.
10
Noise Coupling
The mechanisms by which electromagnetic noise couples between circuits — conductive capacitive and inductive.
13
Filtering
How filters suppress conducted noise on power and signal lines and how to select the right filter.
16
Material Properties
The electromagnetic properties of materials — conductivity permeability and permittivity — and their role in EMC design.
2
Frequency & Wavelength
The relationship between frequency and wavelength and its practical relevance for EMC.
5
Transmission Lines
How signals travel along conductors and the EMC implications of transmission line behaviour.
8
Skin Effect
Why high-frequency currents concentrate at the surface of conductors and what this means for shielding.
11
Shielding
How enclosures and shields attenuate electromagnetic fields and the factors that affect shielding effectiveness.
14
Galvanic Series
The electrochemical compatibility of metals and its relevance to corrosion and contact resistance in shielded enclosures.
3
Time-Domain vs. Frequency-Domain
How signals are represented in both domains and why both views matter for EMC analysis.
6
Electromagnetic Fields
The fundamentals of electric and magnetic fields and how they interact with electronic systems.
9
Components
The EMC behaviour of passive components — resistors capacitors and inductors at high frequencies.
12
Grounding
Grounding principles and strategies for minimising noise and achieving EMC compliance.
15
Triboelectric Effect
How electrostatic charge builds up through contact and separation of materials and its EMC implications.
