Coupling (electronics)
In
electrodynamic
inductive coupling.
Types
Electrical conduction:
- Direct coupling, also called conductive coupling[1] and galvanic coupling
- Resistive conduction
- Atmospheric plasma channel coupling
Electromagnetic induction:
- Electrodynamic induction — commonly called inductive coupling, also magnetic coupling[1]
- Capacitive coupling
- Evanescent wave coupling
Electromagnetic radiation:
- Radio waves— Wireless telecommunications.
- Electromagnetic interference (EMI) — Sometimes called radio frequency interference (RFI), is unwanted coupling. Electromagnetic compatibility (EMC) requires techniques to avoid such unwanted coupling, such as electromagnetic shielding.
- Microwave power transmission
Other kinds of energy coupling:

The circuits we have considered so far may be regarded as conductively coupled, because one loop affects the neighboring loop through current conduction. When two loops with or without contacts between them affect each other through the magnetic field generated by one of them, they are said to be magnetically coupled.
