Pulsed Artificially Created Electrojet
Abstract
The objective of the PACE project is to determine the HED moment required to achieve nT magnetic field at distances from .5-1 Mm from the location of the ground based HED at locations near the magnetic equator. Significant advantage can be gained if the HED radiates in a sneak-through or partial sneak-through mode, in which the observed signal from a magnetic dipole ground return antenna creates a magnetic field that scales as 1/R(2) (naked current) or 1/R(alpha) where alpha is less than 3 instead of the usual 1/R(3) for dipole fields. Since standard magnetic dipole loop antennae (vertical dipole, horizontal current) induce an opposite dipole in the ground, resulting in fields that drop off as 1/R(4), the PACE antenna has a strong scaling advantage over them.
