Transmission Line Equation
The Transmission Line Equation node is the main feature of the Transmission Line interface. It defines the 1D wave equation for the electric potential. The wave equation is written in the form
where R, L, G, and C are the distributed resistance, inductance, conductance, and capacitance, respectively.
Transmission Line Equation
Enter the values for the following:
•
Distributed resistance R (SI unit: Ω/m). The default is 0 Ω/m.
•
Distributed inductance L (SI unit: H/m). The default is 2.5 × 10−6 H/m.
•
Distributed conductance G (SI unit: S/m). The default is 0 S/m.
•
Distributed capacitance C (SI unit: F/m). The default is 1 × 10−9 F/m.
The default values give a characteristic impedance for the transmission line of 50 Ω.
If the Number of signal conductor lines is greater than one, each distributed element is specified as a square matrix whose size equals the Number of signal conductor lines.
