Hello Rui, the only thing happens here is scaling the 4 Maxwell equations under the condition that c0 = 1. The solutions are not unique, you can choose the scaling method, which is more suitable for your problem. (for example, you can let the permittivity as the value in the real world, or keep the length in meter or mm, or if you want to calculate a real current value, you can also keep the current in SI unit).
