WebSurface integral of a vector field over a surface. Author: Juan Carlos Ponce Campuzano. Topic: Surface Web1. The surface integral for ﬂux. The most important type of surface integral is the one which calculates the ﬂux of a vector ﬁeld across S. Earlier, we calculated the ﬂux of a plane vector ﬁeld F(x,y) across a directed curve in the xy-plane. What we are doing now is the analog of this in space.
