Modal Characteristics of Single and Dual Wires Located over a Dissipative Earth.

Abstract

The objective of this research project is to investigate the characteristics of discrete guided wave modes supported by open structures near a dissipative earth. Possible engineering application is found in radar traffic control, airport surveillance and other similar problems. Since the beginning of this contract, considerable progress has been made towards a better understanding of electromagnetic propagation on thin-wire structures located above earth in general, and the characteristics of guided modes on a single or dual line of bare-wires and dielectrically-coated wire in particular. Attention also has been given to the development of excitation schemes for low attenuation modes, to the problem of mode conversion due to irregularities in the immediate vicinity of a guiding structure and to the calculation of radiation loss in the presence of bends among others.
