... field the same result as equation (2.7). This double derivation of the radiated field of the HERTZ dipole antenna was necessary to present the difference between the new and the traditional derivation. The reason for the differences is again – as seen with the examples of moving charges – that the e ...

... mass, length and time. For example, speed is a length divided by time. Force is mass times acceleration, and is therefore a mass times a distance divided by the square of a time. We therefore say that [Force] = MLT−2. The square brackets mean: “The dimensions of the quantity within”. The equations i ...
