Abstract
This paper presents the characteristics of electromagnetic field uniformity in a reverberation chamber with flat diffusers composed of multiple dielectric materials that can be used as an alternative facility for the analysis, test and evaluation of electromagnetic interference and immunity. The field characteristics and the size of the test volume inside the reverberation chamber with the new diffuser of multiple dielectric materials are simulated and analyzed at $2.5{\sim}3$ GHz band. The FDTD method is used to analyze the field characteristics. The field uniformity, polarization characteristics and tolerance are improved by the new diffuser with smaller physical size. The reverberation chamber with flat diffusers composed of multiple dielectric materials shows better electromagnetic performance and larger test volume than normal chamber.
