Frekvenční studie přirozeného elektromagnetického pole

Abstract

This work describes the first extensive results of the shape and frequence investigations of the natural electromagnetic waves measured at slope deformations in greater detail. The results of this study have shown that the large part of the investigated field is created by the components that don’t belong to natural fields according to the classical geophysical dividing. In fact they are spurious signals due to the associated effects connected with the broadcast of various types of the anthropogenic electromagnetic signals. The authors of this paper have succeeded in discovering signals that can’t be unambiguously reported to be the responses of man-made electromagnetic fields.
