Microwave simulator based on the FEM by use of commercial tools

摘要

The authors have developed several analysis methods based on the FEM for microwave circuits, and have shown the validity and usefulness of the analysis methods. In this work, a microwave simulator having the analysis methods as solvers and commercial tools as pre- and post-processors is made. This simulator runs on Word97 of Windows98. Using this simulator, the transmission characteristics of an H-plane waveguide junction, the eigenmodes of a shielded planar circuit, and the eigenmodes of a three-dimensional cavity resonator are analyzed, and the computed results are presented in graphs and plots of the field distribution.
