The theory of open- and short-circuited transmission lines – often referred to as stubs – was addressed in Section 3.16. These structures have important and wide-ranging applications. In particular, these structures can be used to replace discrete inductors and capacitors in certain applications. To see this, consider the short-circuited ...A lossless line is defined as a transmission line that has no line resistance and no dielectric loss. This would imply that the conductors act like perfect conductors and the dielectric acts like a perfect dielectric. For a lossless line, R and G are both zero, so the equation for characteristic impedance derived above reduces to:Application: Capacitively Loaded Transmission Line. A long lossless transmission line with a characteristic impedance of 50 Ω is terminated with a 1 μF capacitor. The length of the line is 100 m and the speed of propagation on the line is c/3 [m/s]. At t = 0, a 100 V matched generator is switched on. Calculate and plot: (a)The ideal lossless transmission line has zero resistance while a lossy TL has some small series resistance that distorts and attenuates the propagating signals. In practice, all TLs are lossy. Modeling of lossy TLs is a difficult challenge that is beyond the scope of this book. Since the focus of this book is only on practical problem-solving ...

Propagation constant. The propagation constant of a sinusoidal electromagnetic wave is a measure of the change undergone by the amplitude and phase of the wave as it propagates in a given direction. The quantity being measured can be the voltage, the current in a circuit, or a field vector such as electric field strength or flux density.Schematic of a wave moving rightward down a lossless two-wire transmission line. Black dots represent electrons, and the arrows show the electric field. One of the most common types of transmission line, coaxial cable. Propagation constant.
