An investigation of electromagnetic field inside a moving wall mode-stirred chamber

A generalised solution to the electromagnetic field excited by a current source inside a moving wall mode-stirred rectangular chamber is presented by using the dyadic Green´s function for the chamber. A detailed discussion of the field inside the chamber is given. The polarization of the field is also illustrated. The solution shows that a uniformly random electromagnetic field, both in amplitude and polarization, can be obtained by a suitable choice for the excitation and the stirrer. This is in good agreement with the previous experimental results
