The wave or radiation impedance of an electromagnetic wave is defined as the ratio of its electric to magnetic field intensities, that is, E/H. E is measured in volts per meter and H is measured in amperes per meter. E/H is measured in ohms. The wave impedance in free space is determined by the source of the radiation.
