Abstract

A novel formulation for the calculation of equivalent dielectric constant of multilayer medium with slightly rough interfaces is proposed. The formulation is based on the volumetric perturbation of inhomogeneous medium and the closed-form solution to the problem of electromagnetic scattering from the simplified geometric structure of layered media. And the derivation relies on the reciprocity principle which can use the perturbation of dielectric constant to replace the height fluctuation of rough interface contours. According to the calculation results, the validity of macroscopic dielectric constant model is tested to a certain extent. Furthermore, the simulation of four-layer soils and ice-covered regions will be directly applicable for active microwave remote sensing inversion.
