摘要：
Potential theory is used to derive closed-form expressions for the energy flux in propagating polychromatic surface gravity waves for water of infinite depth. The energy flux vector has been obtained as convolution-type integrals of the wave-elevation time series at one point on the surface. An expression for the integrated flux through a vertical surface is also given. It is shown that the integrated flux cannot be negative at any instant in time.
