To calculate the power that can be extracted from deepwater waves, we shall simplify
the rigorous mathematical treatment. It shows that for a surface wave of amplitude a and
wave number k, the radius r of particle motion below the surface is
rae
kz
=
(11.4)
where
k = 2π/λ
z is the distance below the surface, as shown in Figure 11.24
The vertical displacement from the average position as a function of time t is

and the horizontal velocity component,

Then, P
