Electromagnetic coupling

Electric field coupling (also called capacitive coupling) occurs when energy is coupled from one circuit to another through an electric field

Two circuits above a signal return plane.

Magnetic field coupling (also called inductive coupling) occurs when energy is coupled from one circuit to another through a magnetic field

Two circuits above a signal return plane

For instance

  • magnetic coupling between multiple inductors
  • capacitive coupling between multiple transmission lines
