Abstract : In present report, the field structure of dipole transmitters is examined as dependent on the working frequency. At given technical possibilities and under the condition that the electrical parameters of a homogeneous medium are independent of the frequency, there exists an optimum working frequency for the transversal field component of a magnetic dipole. Given technical possibilities mean that the dipole moment at the transmitter side can be kept constant in the frequency region under consideration, and that the sensitivity available on the receiver side is the same for any frequency. The optimum frequency at typical experimental values of conductivity and dielectric constant lies at 100 kcps. This behavior of field strengths is the same also in the case of an electrical dipole, when considered qualitatively. (Author)
