Abstract (en)
A device is disclosed for generating an electromagnetic field (E, H) having the electrical field vector (E) or the magnetic field vector (H) concentrated around a target axis (z). The device includes an electromagnetic field source (16, 18; 21) for inducing a near-field configuration of the electromagnetic field having flux lines (F) of the electrical field vector (E) or the magnetic field vector (H) that have components both parallel to the target axis (z) and orthogonal thereto (x, y). A suppressor element (22; 22'), such as e.g. a ferrite or a dielectric disc is coupled to the field source (16, 18; 21) for suppressing the components of the flux lines (F) of the electrical field vector (E) or the magnetic field vector (H) that extend orthogonal to the target axis (z).
