Summary:Recent advances in forward modeling of the electromagnetic
scattering properties of sea ice are presented. In particular, the
principal results include the following: (1) approximate calculations of
electromagnetic scattering from multilayer random media with rough
interfaces, based on the distorted Born approximation and radiative
transfer (RT) theory; (2) comprehensive theory of the effective complex
permittivity of sea ice based on rigorous bounds in the quasi-static
case and strong fluctuation theory in the weakly scattering regime; (3)
rigorous analysis of the Helmholtz equation and its solutions for
idealized sea ice models, which has led in the one dimensional (1D) case
to nonlinear generalizations of classical theorems in Fourier analysis.
The forward models considered incorporate many detailed features of the
sea ice system and compare well with experimental data. The results have
advanced the general theory of scattering of electromagnetic waves from
complex media as well as homogenization theory, which relates bulk
properties of composite media to their microstructural characteristics.
Furthermore, the results have direct application to microwave remote
sensing and serve as the basis for inverse algorithms for reconstructing
the physical properties of sea ice from scattering data
