<p><b>New page</b></p><div>When a wave in incident at an angle <math>\theta </math><br />
we have the wavenumber in the <math>y</math> direction is <math>k_y = \sin\theta k_0</math><br />
where <math>k_0</math> is as defined previously (note that <math>k_y</math> is imaginary). <br />
<br />
This means that the potential is now of the form <math>\phi(x,y,z)=e^{k_y y}\phi(x,z)</math><br />
so that when we separate variables we obtain <br />
<center><br />
<math><br />
k^2 = k_x^2 + k_y^2<br />
</math><br />
</center><br />
where <math>k</math> is the separation constant calculated without an incident angle.</div>Meylan
