| Summary: | 碩士 === 國立臺灣海洋大學 === 電機工程學系 === 94 === The thesis is based on the generalized method of moment(GMoM). The electric field integral equation (EFIE) , magnetic field integral equation (MFIE) and combined field integral equation (CFIE) are used to solve for the scattering field of a three-dimensional complex object of arbitrary shape modeled by triangularly faceted surfaces and they are transformed into matrix equations. The conjugate gradient method (CGM) is used to iteratively solve the matrix equation for the unknown expansion coefficients of the surface electric and magnetic current. We use the multilevel fast multipole algorithm (MLFMA) to speed up the matrix-vector multiplication in the CGM. In addition , we incorporate feed models and several boundary conditions in the program. Electromagnetic scattering and radiating problems by three-dimensional objects of complicated structure can be readily solved in a unified fashion.
