Title: Poynting vector of an ELF electromagnetic wave in three-layered ocean floor
Abstract: In the present study, the Poynting vector of an ELF electromagnetic wave in the presence of a three-layered ocean floor is treated both analytically and numerically. It is verified that the derived locus of the Poynting vector in a three-layered region reduces to exactly the same form for a two-layered region once the thickness of the intermediate layer decreases to zero. When studying the magnitude of the Poynting vector, it is found that the locations of the turning points accurately match the coordinates of maximum penetration. Moreover, despite that the lateral wave can reach a larger depth of penetration as the propagation distance increases, the electromagnetic field at the receiving point will also bear greater attenuation. Figuring out the required penetration depth before determining the location of the receiver is a possible way to ease this issue.
