INTERMEDIATE FIELD REGION

For an antenna , the transition region--lying between the near-field region and the far-field region --in which the field strength of an electromagnetic wave is dependent upon the inverse distance, inverse square of the distance, and the inverse cube of the distance from the antenna. ( 188 ) Note: For an antenna that is small compared to the wavelength in question, the intermediate-field region is considered to exist at all distances between 0.1 wavelength and 1.0 wavelength from the antenna. Synonyms intermediate field, intermediate zone, transition zone.
