“…Transients in nonuniform transmission lines have been attacked by different methods, e.g., Laplace transform methods [7], methods of spline [9], methods of characteristics (2,9], finite difference methods [lo], spectral methods [ll], and recently, by scattering parameters [18]. Among these methods and approaches, the most general and accurate, possessing a physical interpretation, is the method of characteristics (frequently called the traveling wave method).…”
