Abstract:
One example discloses a first near-field electromagnetic induction (NFEMI) device, including: a controller configured to be coupled to an NFEMI antenna and to a structure; wherein the NFEMI antenna includes electric (E) near-field and magnetic (H) near-field generating and/or receiving portions; wherein the controller is configured to modulate a ratio of energy sent to and/or received from the electric and magnetic portions; wherein the controller is configured to receive a signal corresponding to whether the structure is between the first NFEMI device and a second NFEMI device; and wherein the controller is configured to decrease the ratio of energy sent to and/or received from the electric (E) portion as compared to energy sent to and/or received from the magnetic (H) portion if the structure is between the first and second NFEMI devices.
