ELF Electromagnetic Wave Across Sea Level from HED in Three-layered Medium

Exploring the electromagnetic wave propagation in the marine environment is extremely important in ship communication and marine information monitoring. Understanding the propagation law of electromagnetic waves in the marine environment plays a theoretical guiding role in the application related to the propagation of electromagnetic waves. This paper discusses the influence of the seabed medium in the stratified marine environment on the electromagnetic field in the air radiated from the low-frequency horizontal electric dipole (HED) located at the seawater. The conclusion shows that the existence of seabed media will affect the magnitude of electromagnetic field amplitude on the sea surface, but will not change the law of electromagnetic wave propagation in the air except different field intensity.
