Attenuation Function

The directional dependence of the calculated surface impedance on a nonparallel stratified conductor is pointed out. In spite of this dependence, the reciprocity theorem is not violated when the mutual coupling between two dipoles is considered.

Abstract Artificial and natural electromagnetic structures with strongly inductive surface impedance are considered. The object of the research is layered structures of the “dielectric-conductor” type. The existence of impedance media with the maximum possible phase of a strongly inductive impedance in the range from a few hertz to tens of gigahertz has been established. The results of numerical modelling of the propagation of decimeter radio waves over a plane strongly inductive surface are presented, these numerical results are necessary for calculating the attenuation function W and the field level E of microwave electromagnetic waves.

This paper presents a new integral equation to calculate the attenuation factor near the Earth's surface. An expression for the attenuation function computation at arbitrary heights is derived and the distance dependences of the attenuation factor are presented. The correspondence of the numerical results with analytical calculations for the planar and spherical surface is shown. The results for the real terrain profile are given.
