✦ Synopsis

The calculation of the radiation field D(x, y, z) produced by a uniform polygonal source is of considerable practical importance. Fock showed that there are advantages in replacing the traditional surface integral by a contour integral, using Stokes' theorem. This innovation, however, has not yet penetrated very deeply. It seemed worthwhile, therefore, to systematize the procedure and to show how easily results can be obtained by the Pock method.

An incidental conclusion of the paper is that the radiation field from a polygonal source often differs by less than one per cent from the field produced by a circular disk of the same area. Thus the simple disk formula can often be substituted for the more complicated polygonal formula.
