Abstract :
This paper focuses on evaluation of sea foam effective dielectric constants at microwave frequencies using Maxwell Garnett’s and Bruggeman’s methods. Satellite-based geophysical retrievals of environmental variables from radiometric measurements at microwave frequencies require increasing demands for accuracy. Geophysical retrievals such as sea surface emissivity and brightness temperatures of the ocean can be evaluated accurately if the effective complex dielectric constants of sea foams are well evaluated.An overview of the classical mixing rule and evaluation of complex effective dielectric constant of seawater at various microwave frequencies were reported. Results of the complex effective dielectric constant of sea foam using Maxwell Garnett’s and Bruggeman’s methods were also reported.
