多端口平面传输线连接器的数值研究

Efficient Numerical Analysis of planar Transmission Line Multiport Connectors

本文提出了研究多端口平面传输线连接器的数值方法；该方法首先将平面传输线等效为波导模型，然后采用边界元法对等效后的波导不连续情况进行分析，计算了任意端口之间任意模式的散射参量。文中所述过程具有推导简单、计算量小、处理问题灵活等特点。

In this paper,a numerical method,which is a combination of the eqtivalent waveguide model and the boundary-element method, is presented for the investigstion of planar transmission line multiport connectors. The multimode s-parameters are calctlated with good accuracy from a simtle identification in the system of equations given by the boundary-element approach
