通孔到基片集成波导过渡(via-to-SIW transition ) 的等效电路参数提取: Systematic Modeling and Characterization.pdf

A model and parameter extraction method for a via-to-SIW transition is presented. The model is derived from an
analysis of experimental data and full-wave simulations, allowing to obtain the equivalent circuit parameters for the via including
its interaction with the SIW.

文章不错。

研究一下，最近要做SIW功分器

研究一下。。谢谢。
