Near field and far field are terms commonly used in various fields, including physics, engineering, and telecommunications, to describe regions in relation to a source of waves, such as electromagnetic waves, sound waves, or other types of waves. ### Near Field The near field refers to the region close to the source of the wave where the behavior of the field is not specified by simple wave equations. In this zone, the wave typically does not propagate in the same way as it does in the far field.
