In recent years, microwave engineers faced with making precision measurements of antenna patterns and the weak electric field intensity of model diffraction tests, for example, have found it increasingly difficult, if not impossible, to find sufficiently interference-free environments for their experiments.　The performance requirements of an indoor microwave anechoic test range are quite similar to those of an audio anechoic chamber.　And several outdoor test sites have had to be provided with extensive absorbing fences or ground pads in order to reduce reflections to a tolerable level.　This paper describes the fundamental characteristics of the non-magnetic absorber ”SANS REFLETER” at 9 Gc/s and a few considerations on the measurement of its performance.
