Abstract : A study is presented of the electromagnetic fields caused by electric dipoles located within a highly conductive medium such as the sea. The basic method used is described as the plane wave approach. The purpose of the plane wave approach is to use the basic notions of plane waves to determine useful information about the seaair problem without resorting to asymptotic expansions. The theory of nonuniform electromagnetic plane waves is presented. Two plane wave boundary value problems pertaining to the seaair problem are studied. The transmission coef icients are used to construct the field transmitted into the air by a submerged electric dipole. Some fundamental properties of fine submerged antenna structures are developed. The theory of nonuniform plane waves is extended to the n-layer problem.
