Animation 7: Radiation of the Hertzian dipoleA Hertzian dipole consists of a negative point charge at the coordinate origin and a harmonic-moving positive point charge at a(t);
In the far-field approximation, the vector potential can be directly integrated. Above, the electric field lines are shown in the x-z plane. Further details can be found in Chap06_4 .
