The integral L 0 e iΞ½Ο† (s,t) f (s) ds with a highly oscillatory kernel (large Ξ½, Ξ½ is up to 2000) is considered. This integral is accurately evaluated with an improved trapezoidal rule and effectively transcribed using local Fourier basis and adaptive multiscale local Fourier basis. The representati
