Abstract

The ideal testing environment for RF equipment is non-reflective, non-reverberant, and provides suf- ficient isolation from the ambient RF environment. A conducting enclosure provides a very high degree of isolation from the environment but is, by defini- tion, a reflective and reverberant environment because the reflection coefficient at the boundary is near one. Therefore, for ideal RF testing, some means is necessary to reduce the reflection coeffi- cient at the boundary of a conducting enclosure while maintaining a given level of attenuation from outside fields.
