ABSTRACT:
The device is of the type comprising a closed test cell the periphery of which is defined by an outer conductor of a TEM waveguide constituted by a tubular casing. An inner conductor of the waveguide extends within the cell. The casing has at least one intermediate portion of uniform rectangular cross-section, in which there is a test region for accommodating an object under test. At least in the intermediate portion, the inner conductor has a substantially arcuate transverse profile, the concave side of which faces the object under test. The inner conductor is preferably constituted by an array of transversely spaced-apart parallel wires arranged so that the array has the said arcuate profile.
