The Propagation of Geomagnetic Micropulsations into a Two-Layer Conducting Earth
Abstract
Geomagnetic micropulsation fields at the earth's surface are characterized by spatial variations along the surface that are associated with non-uniform plane waves in the Fourier spectrum representation of these near fields. Using both a single micropulsation frequency and a single spatial frequency in a two-layer conducting earth, expressions are derived for the field attenuation, the ratio of vertical to horizontal field, and the surface impedance. Numerical results are presented for a seawater layer over an earth bottom for a spatial frequency that is prominent in many micropulsations.
