Electromagnetic Radiation in Sea Water
Abstract
A knowledge of the effects of sea water on electromagnetic waves is essential to any study of torpedo command guidance systems using either radio or wire links. This report presents a set of theoretical curves to illustrate the transmission of electromagnetic waves in a sea water medium. The curves presented are for sea water at 17 deg C. They are intended as a theoretical starting point for further discussion or investigation. Curves considered to be most descriptive and useful, and included in this report, are: intrinsic impedance of sea water medium versus frequency; wave length of electromagnetic radiation in sea water; attenuation versus frequency; variation of transmission coefficient with angle of incidence - for both vertical and horizontal polarization of the incident wave; and attenuation to be expected when loss through the interface and through sea water are accounted for.
