Dielectric constant of seawater
WebTo determine the dielectric constant of seawater, a brass microwave cavity that operates relative dielectric constant of the seawater sample and at L-band (1.413 GHz) has been employed in the experiments. The measurements have been made in support of the Aquarius space-borne satellite mission with its goal of measuring sea surface salinity. WebAug 1, 2008 · The complex dielectric constant of sea foam obtained with these mixing rules is presented and the dependence of foam permittivity on foam void fraction, radiation frequency, sea surface temperature, and salinity is reported.
