Induction vs Radiansphere - What's the difference?

induction | radiansphere |

As nouns the difference between induction and radiansphere

is that induction is an act of inducting while radiansphere is a spherical region of radius λ/2π around a small dipole electromagnetic antenna. This is the distance at which the induction and radiation terms are equal in magnitude. Inside, the induction terms dominate. In radio antenna theory the radiansphere is a convenient definition for the boundary between near-field and far-field regions.

    radiansphere

    English

    Noun

    (en noun)
  • A spherical region of radius ?/2? around a small dipole electromagnetic antenna. This is the distance at which the induction and radiation terms are equal in magnitude. Inside, the induction terms dominate. In radio antenna theory the radiansphere is a convenient definition for the boundary between near-field and far-field regions.
  • * 1959 , , "The Radiansphere around a Small Antenna", Proceedings of the IRE , August, Volume 47, Issue 8, page 1325
  • *:"The "radiansphere'" is the boundary between the near field and the far field of a small antenna. Its radius is one radianlength (?/2?), at which distance the three terms of the field are equal in magnitude. A "small" antenna is one somewhat smaller than the '''radiansphere''', but it has a "sphere of influence" occupying the ' radiansphere .
