The Implementation and Development of a Time-Domain Model of Dispersive Transmission Line

In the time domain, the accurate and efficient simulation of lossy and dispersive transmission lines is still a problem. Therefore, a time-domain model of the dispersive transmission line based on series approximation and recursive integration was implemented into APLAC. In addition, model was developed to take into account the initial state. The model was tested carefully and results obtained were accurate enough compared with results based on the frequency-domain model. The recursive integration made the calculation efficient. The new model improves the transmission line simulation capability of APLAC.
