=== Reflection and Transmission Coefficients ===

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