摘要：

The paper proposes an efficient hybrid technique based on the finite-difference frequency-domain (FDFD) method and the method of moments (MoM) to study the susceptibility of a terminated microstrip transmission line (MTL) inside a perforated rectangular enclosure. The complex geometry of the inside cavity region is treated by an efficient FDFD method, whereas the unbounded outside region of the enclosure is analyzed by a MoM solution. To account for the relatively thin microstrip dielectric, a nonuniform meshing scheme is adopted for the FDFD method. Also, linear lumped elements connected to the MTL are modeled by changing the related node information in the mesh according to the element type and direction. The validity of the proposed technique is confirmed by comparing our simulation results with those obtained using a commercial finite integration code and measurement results.
