Magnetic flux and lines of force for the Hertzian electric dipole and nonsinusoidal waves

The authors present computer plots of magnetic lines of force for the Hertzian electric dipole excited by sinusoidal currents that radiate to the far-field electromagnetic waves with the time variation of a Gaussian pulse. Plots of lines of force for sinusoidal waves are also presented for comparison. Since the density of the lines of force at any distance from the radiator is proportional to the magnitude of the produced field strength, the derived plots of lines of force show that the Hertzian electric dipole is not an efficient radiator for nonsinusoidal electromagnetic waves
