“…Soil dielectric models relating the dielectric permittivity of a soil to its physical parameters are the essential part of algorithms for retrieving soil moisture from remote sensing data. Due to this reason, numerous experimental programs have been conducted in order to investigate the dielectric behavior of soil-water mixtures in the microwave region (e.g., Abdulla et al, 1988;Bobrov et al, 1989;Boyarskii and Tikhonov, 1995;Boyarskii et al, 2002;Curtis, 2001;Hallikainen et al, 1985;Hipp, 1974;Hoekstra and Delaney, 1974;Ilyin and Sosnovskiy, 1994;Jackson, 1990;Kleshchenko, 2002;Krotikov, 1962;Leschanskiy et al, 1971;Mätzler, 1998;Mironov et al, 1995Mironov et al, , 1997Mironov et al, , 2004Peplinski et al, 1995;Polyakov et al, 1994;Sabburg et al, 1997;Wang, 1980). Soils are random media consisting of soil particles, air voids, and liquid water.…”
