The present disambiguation page holds the title of a primary topic, and an article needs to be written about it. It is believed to qualify as a broad-concept article. It may be written directly at this page, or drafted elsewhere then moved over here. Related titles should be described in Coupling (physics), while unrelated titles should be moved to Coupling (physics) (disambiguation).
Coupling is also important in physics for the generation of plasmas. In electrical discharges, the coupling of an exciting field and a medium creates plasmas. The quality of the coupling of an exciting field of given frequency to a charged particle depends on resonance.
