Abstract :
Examines the various criteria relating to the traditional measurement of microwave absorbing materials. The testing of radar absorbing material is often carried out by using the arch configuration. This is a free-space reflectivity measurement where the sample is interrogated by a pair of horns operating in bistatic mode. Absorber samples of different sizes are compared with identically-sized flat metal plates with regards to their reflectivity. The results of this work are discussed
