Spurious eigenvalues and fictitious frequencies for acoustic problems with the mixed-type boundary conditions by using BEM
碩士 === 國立海洋大學 === 河海工程學系 === 91 === In this thesis, boundary integral equations and boundary element methods were employed semi-analytically and numerically to study on the occurrence of both the spurious eigenvalues and fictitious frequencies for the interior and exterior Helm...
