Abstract :
Electrical mode-stirring in reverberating chambers for EMC is accomplished by antennas which are loaded by variable reactances. The principle is derived from a network model of the chamber, which employs measurable coupling factors. The concept is experimentally confirmed in the GHzrange for a chamber with four conical antennas. One antenna is connected to a generator; the other three antennas are reactively loaded by variable short circuit plungers.
