Abstract:This paper analyzes the mechanism of surface wave suppression for absorbing material and proposes a
novel test system to measure the suppression effectiveness of the absorbing material. Horn antenna is used for radiating
electromagnetic energy to the conducting plane in a grazing angle range from 8 GHz to 12 GHzꎬ and electric field
probe is produced to detect received electromagnetic energy. By comparing test curves which is covered and uncovered
the absorbing material sampleꎬ the surface wave suppression effectiveness of the absorbing material can be obtained.
Two kind of radar absorbing materials are measured by the novel test systemꎬdemostrating the relibity of the system.
