Abstract:

The electrical properties of seawater for ac currents or fields of 1 GHz or higher frequencies are examined with particular emphasis on the effects of relaxation of the charge carriers with the frequency of the applied field. Such effects have not been definitively quantified either experimentally or theoretically. New experiments are conducted but are not conclusive. It is possible that the conductivity relaxation time is similar to the Debye relaxation time making direct observations of this effect difficult. Keywords include Dielectrical properties above one GHz and Microwave.
