This report covers the period from June 1959 through December 1959. During this period, engineering personnel of Cooke Engineering Com pany have conducted intensive research into the problems attendant upon suppression of propaga tion of electromagnetic energy from underground cables by attenuating media. The research has indicated that the parameters which exhibit the greatest effect on the suppression of propaga tion through attenuating media are permeability, conductivity, dielectric constant, and thickness or depth of the medium. The results of the research have shown that if the parameters of the medium are constant at all frequencies with in the range of study, attenuation will increase as the frequency increases. Conclusions made from the calculations and graphs have been prepared for presentation, and a series of ex periments to prove these conclusions proposed. The proposed experiments will, in addition, reveal the behavior of variable parameters which could not be predicted from theoretical studies. Author
