Sommerfeld Diffraction Theory
Diffraction behind a semi-infinite breakwater (Penney-Price):
$$K_D(\xi) = \frac{1}{2}\left|F(\xi_+) + F(\xi_-)\right|$$Fresnel integral: $F(\xi) = \frac{1+i}{2}\int_\xi^\infty e^{-i\pi t^2/2}dt$
$\xi_\pm = \sqrt{2kr/\pi}\sin[(\theta\pm\alpha)/2]$, wave number $k=2\pi/L$
Wave energy flux: $P = \rho g^2 H^2 T/(32\pi)$ [W/m]
