A study on eigenproblems for Helmholtz equation with circular and spherical boundaries by using the BIEM and the multipole Trefftz method
碩士 === 國立臺灣海洋大學 === 河海工程學系 === 97 === In this thesis, the multipole Trefftz method and the null-field integral equation are employed to deal with 2-D and 3-D eigenproblems, respectively. In the chapter 2, the null-field integral equation in conjunction with degenerate kernels and spherical harmonics...
