Abstract :
A non-physical RLGC model for transmission lines is developed through the propagating wave behavior analysis. The non-physical RLGC model is different from the conventional RLGC model with physical RLGC values in the sense that it uses non-physical parameters. The parameters of the non-physical RLGC model are made up of frequency-dependent characteristic impedances and propagation constants. A lossy transmission line is simulated using the non-physical RLGC model. This has been compared with the transmission line equation (quasi-TEM assumption) and TDR measurements, which show good agreement.
