Abstract :
The idea of the source-stirred chamber for performing electromagnetic compatibility measurements is introduced. The electromagnetic field inside the conducting rectangular chamber with arbitrary dimensions is obtained using the corresponding dyadic Green´s function. The computer simulation shows that an evenly homogeneous isotropic field can be created by controlling the excitation source. It is found that the key to perturbing the field effectively lies in shifting the weighting factor of each mode excited in the chamber. The behaviour is analyzed and compared with that of the conventional reverberating chamber, or mode-stirred chamber, leading to some interesting results. It indicates that, instead of the mode-stirrer, an antenna array may be used to generate a uniform electromagnetic field in a rectangular chamber
