ABSTRACT:
In TEM waveguide arrangements such as are used in testing the electromagnetic compatibility of electronic devices in electromagnetic fields, a plate-shaped inner conductor is connected via electrically parallel-connected tubular resistors to an electrically conductive, spherical rear wall. This rear wall is electrically connected to an outer conductor and grounded. Radio-frequency absorbers are mounted on the rear wall for the purpose of absorbing TEM waves, the RF short-point absorbers adjacent to the tubular resistor being smaller than the remaining RF long-point absorbers, in order to reduce the capacitive influence of the tubular resistors. Identical tubular resistors are arranged perpendicular to the plane of the drawing of FIG. 1 in accordance with a current density distribution in such a way that they are more closely adjacent at the edge than in the middle of the inner conductor.
