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.
