Validity of Non-Physical RLGC models for Simulating Lossy Transmission Lines

چکیده

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.

Causal RLGC(f ) Models for Transmission Lines From Measured S-Parameters

Frequency-dependent causal RLGC(f ) models are proposed for single-ended and coupled transmission lines. Dielectric loss, dielectric dispersion, and skin-effect loss are taken into account. The dielectric substrate is described by the two-term Debye frequency dependence, and the transmission line conductors are of finite conductivity. In this paper, three frequency-dependent RLGC models are stu...
