Abstract:

This report constitutes a study of the application of high permeability material to transmission lines intended for underwater communication systems. The application of high permeability material to the exterior of copper conductors is a well known technique of increasing signal losses in a transmission line. The purpose of this study is to determine whether or not the judicious application of the high permeability material can have the reverse effect of lowering the signal losses. Theoretical studies indicate that a hollow copper conductor coated on the inside will exhibit less than normal losses over a discrete frequency range. This effect is investigated in detail. Measurements indicate however, that the advantages gained by the special configuration are overshadowed by practical considerations which severely limit the usefulness of this technique and further study is not recommended.
