【 摘 要 】

A novel approach is implemented for synthesizing equivalent circuits. The approach called the Foster's approach finds its application in the transient simulation of distributed structures.The implementation is analogous to that of a Voltage Controlled Current Source, as it is a natural way to handle Admittance Matrix. The two main features of this method are its guaranteed causality and good numerical stability. The method is tested by simulating a six port power/ground plane and comparing the results with measurements. Also, different analyses types are compared and conclusions are made.
