Analysis, Simulation, and Measurement of Characteristics of a Small Electromagnetic Reverberation Chamber (ERC)

Each Electromagnetic Reverberation Chamber (ERC) is an RF-shielded chamber with conductive walls, typically rectangular that utilizes a specific mode-stirring mechanism to generate statistically uniform electromagnetic fields [1]. The function of an ERC is similar to that of a large microwave oven, designed to create a uniform energy distribution over a presumed surface. An ERC is an electromagnetic measurement tool within a confined environment, similar to an anechoic chamber (AC). However, constructing an ERC is more economical than an AC, although it involves a highly intricate design and analysis process. In addition, ERCs operate under different boundary conditions and exhibit distinct performance characteristics compared to ACs.
