ABSTRACT:
A mode filter for connecting two electromagnetic waveguides with different cross-sections includes a tubular section (4) with openings at both ends. The cross-sections of the openings match the cross-sections of the two different waveguides, while the interior space (11) of the tubular section (4) transitions from one cross-sectional shape into the other cross-sectional shape. Undesirable modes of the electromagnetic waves which are to be transmitted, are minimized by flat elements (14, 15) protruding radially inwardly into the transition region and extending axially along the tubular section (4). The flat elements (14, 15) are made of a material with a high electrical conductivity. The elements (14, 15) are arranged diametrically opposed from each other and aligned in the same plane and separated by a gap (16). The axial length of the flat elements is short in relation to the length of the tubular section (4). The length of the flat elements in the axial direction and the spacing (A) between them is dimensioned so as to minimize the ripple in the group velocity and the amplitude of the wave to be transmitted. The ripple is caused by the superposition of the excited modes.
