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.
Claims8
A device for measuring electromagnetic interference (EMI), of the type comprising a closed test cell the periphery of which is defined by an outer conductor of a waveguide constituted by a tubular casing having rectangular cross-sections and delimited at one end by a supply cusp and at the other end by a transverse wall which is absorbent as regards high frequencies and is associated with resistors for low-frequency dissipation, and an inner waveguide conductor extending within the cell between the supply cusp and the resistors, wherein the tubular casing has at least one intermediate portion of uniform rectangular cross-section including a test region for accommodating an object under test between the inner conductor and one of the peripheral walls of the outer conductor, called the base wall, and in that, at least in the intermediate portion, the inner conductor has a substantially arcuate transverse profile, the concave side of which faces the base wall.
