摘要: The surface displacement in the vicinity of a semi-parabolic canyon was solved over 20 years ago. Previous study presented results only for range low frequencies, with computational difficulty coming from convergence Weber wave functions. We revisit this problem and employ new algorithm computing at much higher frequencies spectral displacements on parabolic by incident SH-waves. A transformation Wronskian allows up to dimensionless frequency then now! In terms wavelength, were computed waves wavelengths five times smaller, or higher, great improvement!
