Finite‐difference — time‐domain analysis of a high‐frequency microwave connector

In this study, the finite‐difference‐time‐domain method (FDTD) is used to analyze a complex packaging component, namely, a high‐frequency microwave connector. Because the FDTD technique is easy to use and very flexible, it can be employed to analyze packaging components whose geometrical configurations are highly complex. In contrast, other approaches, for example, the method of moments (MoM), the method of lines (MoL), and the finite‐element method (FEM), are more difficult to apply to complex geometries. In this article we employ the FDTD method to investigate the scattering parameters of a microwave connector and validate the numerical results by comparing them with measured data.
