%���� of EECS Wavelength and Phase Velocity We can now explicitly write the wavelength and propagation velocity of the two transmission line waves in terms of transmission line parameters L and C: 21 fLC π λ β == 1 v p LC ω β == p The conductors are made of copper. Let their respective charge be + Q and − Q coulombs per metre length. An air or gas dielectric, in which the center conductor is held in place by periodic insulating spacers, can also be used. In practical transmission lines, instead of using heavy and inflexible conductors of large radii, two and more conductors are bundled together to approximate a large diameter conductor, and reduce corona loss. The physical configuration and properties of all the components determines It also gives an estimate of the mismatched loss if the mismatch is specified. 2.coaxial cable of inner radius aand outer radius b.

Transmission lines are majorly classified into three categories: Open-wire transmission line: These are the conductors having 2 lines (wires), that are separated by dielectric medium whose, one end connected to the source and other to the destination. This calculator computes the matched line loss for a transmission line using a model calibrated from data for the transmission line supplied to the calculator.

It is important to determine the characteristic impedance of a twisted-pair cable because this impedance should match the impedance . When the current exceed a certain value the heat generated due to ohmic loss starts to melt the conductor and the conductor becomes longer that results in more sag. A transmission line has a constant line impedance (Zo) when operated well above it's corner frequency.
