Amplitude transmission coefficient in seismic reflection and refraction

Input(s)

$Z_{1}$: Acoustic Impedance of Layer $1\left(\mathrm{~kg} / \mathrm{m}^{2} \mathrm{~s}\right)$

$Z_{2}$: Acoustic Impedance of Layer $2\left(\mathrm{~kg} / \mathrm{m}^{2} \mathrm{~s}\right)$

Output(s)

T: Amplitude Transmission Coefficient (dimensionless)

Formula(s)

$$ \mathrm{T}=\frac{2 * \mathrm{Z}_{1}}{\mathrm{Z}_{2}+\mathrm{Z}_{1}} $$
