This paper presents the electric field characteristics in a reverberation chamber which is an electromagnetic compatibility test facility that uses a stirrer to generate a uniform electric field inside it. In this paper, a diffuser is introduced from acoustics and newly designed to overcome problems of a stirrer. To validate the effect of a diffuser, a composite quadratic residue diffuser and a reverberation chamber are modeled. Then, the field uniformity inside the reverberation chamber is simulated by XFDTD 6.2 simulation program. Simulation results show that the electric field uniformity in the reverberation chamber satisfies the international standard requirement. This shows that the composite quadratic residue diffuser can be substituted for a stirrer.

Field Uniformity

A reverberation chamber, which is a test facility for various electromagnetic compatibility tests, uses a stirrer to generate a uniform electric field inside it. However, a stirrer is a big unit and has difficulties in maintenance. This paper adopted an idea of a diffuser from acoustics to overcome the problems of a stirrer and presents a substitution effect of a diffuser for a stirrer. To validate the substitution effect of a diffuser, a diffuser and a reverberation chamber for 3.0-5.0 GHz band are designed and fabricated. And the real measurement for analyzing the electric field uniformity in a reverberation chamber is done. The measurement results show that the reverberation chamber with a diffuser satisfies the international standard requirement.
