“…General steps are described in [1] for periodically loaded transmission lines, but the method for converting S-parameters to RLGC data is not disclosed. Two analytical approaches are proposed in [3] for single trace transmission line, one requiring the knowledge about material properties and the other requiring S-parameters of two lines with identical cross-section but different line length. The second approach is generalized for an N+1-conductor (N signal conductors with one reference line/plane) transmission line system in [4], in which S-parameters for two identical transmission line systems except for line length are still needed and the length difference between the two transmission line systems needs to be smaller than half wavelength to avoid inaccurate results at resonance frequencies.…”

A general method is proposed to extract frequency dependent RLGC model from simulated S-parameters for multiconductor transmission line structures with periodic threedimensional geometries. It is demonstrated to be robust for both short and long structures and various geometries, and highly efficient for structures with a large number of lines. The method has been tested for transmission line systems with up to 100 lines, which has not been seen in literature. A mode tracking technique is employed to obtain the unique solution for the propagation constant matrix. Equivalent lumped circuit networks are used to ensure extraction accuracy at low frequencies down to DC and provide seamless transition to the general formulation as frequency increases. The Kramers-Kronig relation is applied for causality enforcement and extraction of inductance and capacitance values at infinite frequency.

“…S 11 and S 21 parameters of the single-branch network can be calculated with (9) [36] (20) where T iN represents the T-matrix of the i th single-branch network. Then, the T-matrix of the whole network can be converted to S-matrix using the (12). The S 21 term of the S-matrix gives the transfer function of the whole PLC network, H(f).…”

“…Besides, others are based on time-domain measurements [9][10][11]. Some methods support the calculation of the RLCG parameters from Z c and γ [1,4,12]. Almost other methods estimate Z c from γ extracted from measurements by some assumptions [13][14][15][16][17].…”

“…Also, time-domain measurements are used to extract parameters [13][14][15]. Another part of the studies have proposed a method for calculating the RLGC parameters via the measured Z c and γ [7,12,16]. However, recent studies about extraction of RLGC parameters from measured S-parameters focus on a frequency-dependent RLGC( f ) modeling for transmission lines.…”

-Modeling busbar distribution system as a transmission line is an important subject of power line communication in the smart grid concept. This requires extraction of busbar RLGC parameters, accurately. In this study, a comparison is made between conventional and modified method for the aspect of optimum RLGC parameters extraction in the 1 MHz to 50 MHz frequency band. The usefulness of these methods is shown both in time and frequency-domain analysis. The frequency-domain analyzes show that the inherent power of modified method can eliminate the errors especially due to the discontinuities arise in conventional method. This makes the modeling approach of modified method more advantageous for the busbars due to its robustness against disturbances in the S-parameters measurements which cannot be eliminated with the calibration procedure. On the other hand, time-domain simulations show that the transmission line representation of the modified method is closer to physical reality by handling causality issues.
