| Electromagnetic propagation through sea water is very different from propagation through air because of water's high permittivity and electrical conductivity. Plane wave attenuation is higher through water, and increases rapidly with frequency. With a relative permittivity of about ?r=80, water has the highest permittivity of any material and this has a significant impact on the angle of refraction at the air/water interface. Conductivity of seawater is typically around 5S/m, while nominally fresh water conductivity is quite variable but typically in the mS/m range. Relative permeability is approximately ?r=1 so there is little direct effect on the magnetic field component but conduction leads to strong attenuation of electromagnetic propagating waves. | |
