摘要

In this study, the radiation characteristics of the control source of extremely low frequency (CSELF) horizontal line-current antennas are studied by the reciprocity theorem. The radiation field strength expressions of the CSELF L-type horizontal line-current antenna are derived on the basis of a field-direction coefficient in the spherical earth-ionosphere cavity. The estimation results of the super low frequency/extremely low frequency (SLF/ELF) wave are provided with regard to the conductivity, the propagation distances and the water-depth. The propagation characteristics of the CSELF wave are calculated under different conditions and are compared to Bannister's method. The effectiveness of the proposed method is validated by a case study.
