The system of FOR3D is cylindrical coordinate. While it computes away from source, the distance between two grid points become too large to catch θ-coupling effect and the 3D transfers to Nx2D . Moreover, the resolution becomes low because of less grid points. The main idea to improve the limitation is increasing grid points in the far field. Hence, the θ-coupling terms would not be ignored. The study in this thesis is how to decide the re-grid distance and how to deal with the sound field after re-grid. Chi-Fang chen 陳琪芳 2011 學位論文 ; thesis 43 zh-TW
