S. Savaidis et al., SCATTERING FROM FRACTALLY CORRUGATED SURFACES WITH USE OF THE EXTENDED BOUNDARY-CONDITION METHOD, Journal of the Optical Society of America. A, Optics, image science,and vision., 14(2), 1997, pp. 475-485
A new method for scattering from fractally corrugated conducting surfa
ces is formulated with use of the extended boundary condition method.
Here we expand the fields through generalized Floquet modes and obtain
analytical closed-form expressions for the scattering amplitudes for
both horizontal and vertical polarization of the incident optical and
electromagnetic waves. The accuracy of the proposed method is checked
in several ways, such as comparison with approximate methods previousl
y presented in the literature (Rayleigh and Kirchhoff methods) and cal
culation of the energy-balance parameter. Finally, numerical scatterin
g results from fractal surfaces are provided. (C) 1997 Optical Society
