This paper discusses the electromagnetism properties of the near field chamber, with the relationship between reflected wave and direct wave analyzed. The calculation methods for the properties of the near field chamber are given, which are very useful in solving engineering problems. Finally some typical calculation results of the reflection properties are presented, which show that the zeroreflection range of the horizontal field is larger than that of the vertical fields, and the better the material, the larger the zeroreflection field.
