“…Second and higher-order perturbative developments have also been investigated [9,[26][27][28][29]. It is worth highlighting that pertinent analytical developments following a boundary perturbation approach can be particularly cumbersome [27]; conversely, rigorous second-order volumetric-perturbative developments demand for an appropriate mathematical playground (the distribution theory for discontinuous test functions) [9].…”

This paper addresses the subject of electromagnetic wave scattering in layered media, thus covering the recent progress achieved with different approaches. Existing theories and models are analyzed, classified, and summarized on the basis of their characteristics. Emphasis is placed on both theoretical and practical application. Finally, patterns and trends in the current literature are identified and critically discussed.

“…However, although the numerical method has the advantage of high accuracy, it also has the drawback of large computation compared with that of the asymptotic method. Zamani et al [16] derived the perturbative solution of multilayered rough surfaces and computed the cross-polarized scattering features from them. Iodice et al [17] discussed the scattering from both fractal and classical rough surfaces under the Kirchhoff approximation, and the physical interpretation was also given.…”

The electromagnetic scattering from oil-covered sea surface is investigated by two scale model with the help of Lombardini's oil-covered sea spectrum and the semi-empirical reflection model that takes the oil film into consideration. Firstly, a comparison of the clean and oil-covered sea spectra is made to show the influence of the oil film on the sea surface. Then, the backscattering coefficient from the clean sea computed by the two scale model is compared with the measured data in the reference to validate the accuracy of the two scale model used in this paper. Finally, backscattering features from the oil-covered sea surface are discussed in detail and compared with those from the clean sea. In addition, the influence of the thickness of oil film and fractional filling factor on the backscattering coefficient of oil-covered sea are also studied. The simulated results show that the oil film floating on the sea has remarkable influence on the backscattering coefficient of the sea, compared with those of the backscattering coefficient from the clean sea.

A novel composite rough surface model is presented for describing ground and near sea in adjacent region. Monte Carlo method is used to generate composite rough surface. Gauss spectral function is used to simulate actual ground surface, and JONSWAP spectral function which is combined with shallow coefficient is used to simulate actual near sea surface. Weighted inverse tangent function is presented to connect two regions and smooth the borderline. One dimensional band-limited Weierstrass fractal function is introduced to simulate the actual borderline between ground and near sea in adjacent region. The geometrical models of composite rough surface with linear borderline and fractal borderline are given. By comparing of the contour maps, the geometrical model of composite rough surface with fractal borderline is closer to real environment of ground and near sea in adjacent region than the one with linear ，borderline. The curves of bistatic scattering coefficient of ground, near sea and composite rough surfaces with linear and fractal borderline are compared. This paper presents a novel way to simulate the environment of ground and near sea in adjacent region. Simulation results can use for reference in the fields of remote sensing, detection and inversion of electromagnetic environment.
