Partially prism-gridded FDTD analysis for layered structures of transversely curved boundary

Chieh-Tsao Hwang

Ruey-Beei Wu

Abstract: A partially prism-gridded FDTD analysis is presented to deal with layered structures with curved boundary in transverse directions. It is applied to calculate the scattering paxameters of vias in multilayer packaging. The good agreement of the results with those by other methods verifies the accuracy of this analysis.

Abstract-The coplanar waveguide (CPW)-to-coplanar stripline (CPS) transition is analyzed theoretically and experimentally in this paper. To characterize this transition in the lower frequency band, a simple equivalent-circuit model that consists of uniform and nonuniform transmission lines is established. The elements of this model can all be obtained by the closed-form formulas; hence, this model is suitable for computer-aided-design application. This model is then applied to design and analyze the CPW-to-CPS transitions with various structure parameters. In the higher frequency band, the partially prizm-gridded finite-difference time-domain (FDTD) method is employed to take into account the bond-wire effect as well as the surface-wave leakage and space-wave radiation associated with the transition. In this study, results based on equivalent-circuit model, FDTD simulation, and measurement are compared. Good agreement among these results supports the usefulness of the proposed equivalent-circuit model and also validates the FDTD method. By using the equivalent-circuit model to optimize the transition configuration, the CPW-to-CPS transition with broad bandwidth and low insertion loss may be achieved.
