Fig. 4 Velocity potential field of propagating wave í µí¼(x, y, t) = cos(2í µí¼x − t∕2). Field produced by
formula (19) (top) and linear wave theory formula (bottom)
bers in Fourier transforms were chosen on the interval from 0 to the maximal wave
number determined numerically from the obtained wavy surface. Experiments were
conducted for waves of both small and large amplitudes.
