Reflection and Transmission Coefficients

If we multiply the potential at the left (after subtracting the incident wave) and the right by [math]\displaystyle{ \mathbf{R} }[/math] we can calculate the coefficients in the eigenfunction expansion, and hence determine the reflection and transmission coefficient. where [math]\displaystyle{ z_{j} }[/math] is the value of the [math]\displaystyle{ z }[/math] coordinate in the centre of the panel and [math]\displaystyle{ \Delta x }[/math] is the panel length.
