Statistics of Two Indicators for Multilook Scattering Signals from Multilayered Structures with Slightly Rough Interfaces

Electromagnetic Scattering from Slightly Rough Surfaces with Inhomogeneous Dielectric Profiles

Remote sensing of soil moisture using microwave sensors require accurate and realistic scattering models for rough soil surfaces. In the past, much effort has been devoted to the development of scattering models for either perfectly conducting or homogeneous rough surfaces. In practice, however, the permittivity of most soil surfaces is nonuniform, particularly in depth, for which analytical so...

A New Theorem Concerning Scattering of Electromagnetic Waves in Multilayered Metamaterial Spherical Structures

The proposed theorem in this paper is indicative of a kind of duality in the propagation of waves in the dual media of and in the spherical structures. Independent of wave frequency, the number of layers, their thickness, and the type of polarization, this theorem holds true in case of any change in any of these conditions. Theorem: Consider a plane wave incident on a multilayered spheric...

Theoretical Model of Electromagnetic Scattering from 3d Multi-layer Dielectric Media with Slightly Rough Surfaces

A theoretical model of scattering from three-dimensional arbitrary layered media with 3D infinite rough surfaces based on the small perturbation method (SPM) is derived in the present paper. The scattering field and bistatic scattering coefficient for linear polarized waves are derived respectively. Firstly, the electric and magnetic fields in each region of the layered structure are expanded i...
