Abstract
A magnetic device couples a main conductor of a TEM line and a waveguide forming a .lambda.g/2 resonator and procuring the propagation of an electromagnetic wave. The main conductor is fixed to a wall of the waveguide and extended by a pin inside the waveguide. The device comprises a tuning screw penetrating into the waveguide near the free end of the pin and perpendicular to the pin and an iris around and centered on the pin. The iris is closed on the side on the wall and its interior volume forms a zone in which the wave of the associated magnetic field is evanescent. The median axis of the tuning screw is in the plane of the aperture of the iris.
