The reflection coefficient can be calculated using: Γ Γ = Z 2 − − Z 1 Z 2 + Z 1 , where Γ Γ (Gamma) is the reflection coefficient (0 denotes full transmission, 1 full reflection, and 0.5 is a reflection of half the incoming voltage), Z 1 and Z 2 are the impedance of the first component (from which the wave enters) and the second component, respectively.
