碩士 === 國立交通大學 === 電信工程研究所 === 107 === In this thesis, a validation process is proposed to prove that the Asymptotic Corrugation Boundary Conditions (ACBCs) analysis method can be used for obtaining the electromagnetic field of longitudinally corrugated conical. As a contrast, the numerical field generated by the numerical simulation program is used to compare with the analysis field generated by the ACBCs analysis method. With the favorable similarity between the analysis field and the numerical field, it is shown that the scope of the ACBCs application can be expanded to the spherical coordinate system. The existence of corrugation results in the variation of origin propagation mode. The TE modes of the smooth cone turn into the new propagation mode.
