Abstract

The directions of at least two fibers arranged at a tag are detected to identify the tag and an item intended to be attached thereto. The fibers have an impedance for high frequency electromagnetic waves, which impedance is dependent on a magnetic field at the fiber. Electromagnets generate a modulation magnetic field having an amplitude modulated magnetic component with a first frequency; and a bias magnetic field for counterbalancing any constant magnetic fields parallel to the direction of the fiber. A microwave transmitter directs a frequency modulated microwave signal towards the fiber via a transmitting antenna. The microwave reflected by the microfibers is received by a receiving antenna coaxial with the transmitting antenna and is used to identify tag by determining the orientation of the fibers.
