A reverberation chamber is capable of generating and measuring electromagnetic fields and is used for electromagnetic compatibility test evaluations of electrical and electronic equipment and systems. While the mechanical stirring type is generally the mainstream, a vibrating intrinsic reverberation chamber (VIRC), which is based on an electromagnetic shielding tent made of flexible conductive fabric, is attracting more interest because it is less expensive and is able to perform in-situ tests. In this article, we presented a VIRC configuration and measured its basic characteristics, i.e., the number of independent samples, the goodness of fit to the Rayleigh distribution and the field uniformity, depending on the wall shaking amplitude as a stirring condition. The measurement results contribute to derive a guideline for the VIRC design, i.e., the wall shaking amplitude should be more than one-eighth of the wavelength at the test frequency.

墙体振动幅度对混响室固有振动特性的影响

混响室能够产生和测量电磁场，用于电气电子设备和系统的电磁兼容性测试评估。虽然机械搅拌类型通常是主流，但基于柔性导电织物制成的电磁屏蔽帐篷的振动固有混响室（VIRC）由于成本较低且能够在原位进行而吸引了更多人的兴趣。测试。在本文中，我们提出了 VIRC 配置并测量了其基本特性，即独立样本的数量、瑞利分布的拟合优度和场均匀性，具体取决于作为搅拌条件的壁振动幅度。测量结果有助于得出VIRC设计的指导原则，即墙壁振动幅度应大于测试频率下波长的八分之一。
