WebMay 7, 2024 · The reflection just happens off of the source end, not at the load end. In reality, the reflection coefficient is never equal to zero at all frequencies, which is why we use S-parameters, specifically S11 or return loss, to describe reflections over a broad range of frequencies. S11 (Return Loss) WebThe formula for EM reflection at the interface shown in the figure is ∣E1r E1i∣ = Γ = Z2−Z1 Z2+Z1 (2) This is an E-field reflection coefficient and represents the ratio of the amplitude of the E-field of the reflected wave to that of the incident wave. The acoustic reflection coefficient will have the same form using the acoustic impedances.
