Computer programs are developed to calculate the electric field intensity at one point in space due to an electric dipole at another point in space, in the vicinity of a conducting body of revolution. The programs are valid both external and internal to the conducting surface. Hence, they may be used to compute not only radiated and scattered fields, but also fields internal to resonant cavities. The current on the conducting body is computed as an intermediary step in the program. The solution is obtained by the method of moments applied to the potential integral equation, and involves inversion of the generalized impedance matrix. The principal limitations to the solution are due to the matrix computation and inversion, which requires that the generating contour be at most several wavelengths long. Some examples of computations for spheres, disks, and cone-spheres are given to illustrate the programs.
