The wave equation also holds for an ideal string, if represents the transverse displacement, is the tension of the string, and is its linear mass density. The wave equation ( 1 ) follows from the more physically meaningful telegrapher's equations [ 24 ]:This section introduced the telegrapher’s equations for a pair of coupled lines in a form that is an extension of the telegrapher’s equations of a single line but with the \(L\) and \(C\) of a single line replaced by \(2\times 2\text{ L}\) and \(\text{C}\) matrices. It is no longer necessary to deal with fields and a circuit model can be used.An analytical solution of the coupled Telegrapher's equations for the voltage and current on a homogeneous lossy transmission line is presented. The resulting expression is obtained in the form of an exact time-domain propagator operating on the line voltage and current.

Very good accuracy is obtained if the length of a subsection is no more than one-twentieth of a wavelength. The full transmission line model is the cascade of many transmission line subsections (e.g. see …

The Cattaneo or telegrapher's equation describes the crossover from initial ballistic to normal diffusion. Here we study and survey time-fractional generalisations of this equation that are shown to produce the crossover of the mean squared displacement from superdiffusion to subdiffusion.

Equations 2.17 are in time domain. e^(jwt) is the representation of a sinusoid in the time domain.. Equations 2.18 are in the phasor domain. In the phasor domain, the sinusoid is assumed - a phasor represents the amplitude and phase of a sinusoid, but a phasor is NOT a function of time and thus does not include a time domain represenation of a sinusoid.
