The real part of the propagation constant is the attenuation constant and is denoted by α (alpha). It causes signal amplitude to decrease along a transmission line. The natural units of the attenuation constant are Nepers/meter, but we often convert to dB/meter in microwave engineering.
Similarly, you may ask, what is wave 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.
What is normalized propagation constant?
Propagation Constant. For example, the propagation constant is sometimes understood to be only the imaginary part of the quantity defined above, i.e., β. It is then also common to introduce a normalized propagation constant which can only vary between 0 and 1.
What is constant propagation in compiler design?
Constant propagation is the process of substituting the values of known constants in expressions at compile time.
