Sažetak
The Green's functions for corrugated surfaces have been derived by using the asymptotic corrugation boundary conditions. The assumption is that the periodicity of the corrugations are small compared to the wavelength. The Green's functions are derived in the spectral domain. The poles of the spectral Green's functions give the information about surface waves. In a wide frequency range there is no surface waves in the direction transverse to the corrugations. At central frequency the surface wave is strongly localized in and propagating along the corrugations passing near the source, and its magnitude does not decay with distance. For other frequencies the surfaces waves spread and their magnitude decay. The presented Green's functions are helpful in analyzing plane corrugated surfaces when the plane wave model is not sufficient, e.g. when the source is near the surface. This paper is done while Zvonimir Sipus was a Ph.D. Student at Chalmers University of Technology, Gothenburg, Sweden
