WebIn the case of a short circuited load (ZL=0{\displaystyle Z_{L}=0}), one finds Γ=−1{\displaystyle \Gamma =-1}at the load. This implies the reflected wave having a 180° phase shift (phase reversal) with the voltages of the two waves being opposite at that point and adding to zero (as a short circuit demands).
