Abstract

Abstract: Composite electromagnetic scattering of 1D band-limited Weierstrass fractal layered rough land surface and a conducting column with rectangular cross-section is studied with FDTD.Composite scattering coefficient with varying scattering angle is obtained based on bistatic scattering coefficient.Influence of root-mean-square of height fluctuation,dimension of fractal,parameters of the middle layer medium,lower medium and conducting column with rectangular cross-section on composite scattering coefficient is discussed.

Key words: composite electromagnetic scattering, 1D band-limited Weierstrass fractal land surface, layered medium, FDTD
