Experiments on the effect of reflections from EUT set-up tables by materials in radiated emission measurements above 1 GHz to 18 GHz

In VCCI Technical Requirements Edition 3 (V-3/2015.04), Appendix VII considers the effect of EUT set-up tables by materials in radiated emission measurements above 1 GHz to 6 GHz. Evaluations for the following materials are given therein from the results of experiments based on the test method defined in CISPR 16-1-4 Edition 3.0 (2010) [1] : normal density styrene foam block, wood, fiber reinforced plastic (FRP), low density styrene foam block with foaming ratio of 30 times, and low density styrene foam block with foaming ratio of 50 times.
