The effect of resonance phenomena on the characteristics of a chamber

摘要

This paper describes the study of the effect of resonance phenomena on the chamber's characteristics, which mainly refers to the normalized site attenuation (NSA). The NSA test results of a 12.6×7.8×6m{sup}3 chamber are presented as an example to discuss the influence of resonance phenomena on the NSA characteristic of the chamber. A new structure of a chamber is put forward to eliminate the influence of the resonance phenomena and improve the NSA characteristic of the chamber.
