A GENERAL ANALYSIS OF NATURAL ENVIRONMENTAL EFFECTS ON ELECTROMAGNETIC RADIATION UTILIZED FOR COMMUNICATIONS
Abstract
The earth and its atmosphere provide a highly complex environment for the propagation of electromagnetic waves. A convenient method to study the interply between this environment and propagating electromagnetic signals is to isolate various quasi-homogeneous regions of the earth-atmosphere system, and study the effects they have on different frequency signals. The troposphere, the ionosphere, the oceans and the solid crust are such quasi-homogeneous subdivisions. This report presents a short review of the physical make-up of each of the subdivisions important to radio propagation, together with the most important effects each has upon the propagation of electromagnetic signals.
