near zone n. (also near-zone field) = near field n.

ΚΠ

1964 R. F. Ficchi Electr. Interference iii. 26 The induction or near-zone field, is that area immediately around the source volume in which, and on which, charge and current density are non-vanishing.

1973 C. W. Misner et al. Gravitation 997 (caption) Outside the source—but in the near zone (R ≦ r ≦ ƛ)—the ‘stress-energy pseudotensor’ t^μν dies out.

1978 IEEE Trans. Antennas & Propagation 26 509/1 The near-zone fields of the sinusoidal surface monopole are presented in terms of exponential integrals.

1992 Proc. Royal Soc. 438 354 The kind of approximations considered here are expected to be valid only in the near zone; to get a more complete picture they should be matched to post-minkowskian approximations which are good in the far zone.
