Figure 3-27. Instantaneous Values of Incident and Reflected Waves on an Open-Ended Line
3-106. In waveform (4) of figure 3-27, the incident wave is at a maximum
negative value at the end of the line. The wave has moved another 45 degrees
to the right from the wave in the preceding illustration. The reflected wave
has also moved 45 degrees, but to the left. The reflected wave is in phase with
the incident wave. The resultant of these two waves, shown by the dark line,
again has a negative maximum at the end of the line and a positive
maximum 1/2λ from the end of the line. Notice that these maxima have a
greater amplitude than those in waveform (3).
