A moment-free Filon-based boundary element method for ship wave evaluation and time–frequency analysis
To overcome challenges associated with evaluating the highly oscillatory Fourier–Kochin integrals in ship wave computations, we develop a Moment-Free Filon-type Method (MFFM). Through phase transformation, the MFFM converts kernel functions into quadratic Fourier integrals, reducing evaluation to quadratic interpolatio...
