the ampltitude of capillary wave
 
Hi,all. Does anyone read the paper of Juseok kim, 2005? ------" A continuous surface tension force Formulation for diffuse interface models", JCP, 2005.

From Eq. (32), the amplitude a(t) should be a complex number. Thus, I plot the real value of amplitude from theory.It seems the angular frequency from the figure is not the same as that of theory.

I got these values for the a(t) in the paper, check it out. And about the values of a(t), I sent an email to you already.

Thanks. However,I did not want these data. It is no use.

try to solve it by using mathematica not matlab.
