In the near-field zone of an electronic device the electric and magnetic waves are not synchronized in phase and in vector orientation, so the character of the electromagnetic field is highly inhomogeneous. In areas where de-coupled electric and magnetic waves become synchronised in phase and spatial orientation, an unwanted signal propagating to the far field is formed. In the presented study the phase and vector distributions of de-coupled electric and magnetic fields were measured using E- and H- near-field vector probes. The test results were analysed for phase correlation between electric and magnetic waves.
