SLF Electromagnetic Fields in Stratified Media

Abstract:

SLF waves travel in the air as vertical polarized vaves while as horizonal polarized vaves in the seawater,which have less attenuation than VLF waves. It propagates as lateral electromagnetic wave from seawater into air,whose energy will be concentrated on the interface. Comparisons of electromagnetic fields generated by vertical electric dipole in the air and horizonal electric dipole in the sea have been done.The results indicate that: (a) unit vertical electric dipole in the air is better than unit horizonal electric dipole in the sea. (b)when the receiver is below the boundary,the sources in the air provide stronger E field intensity than the sources in the sea do. (c)in the near field(1000km), underwater transmitting is hard to be achieved.
