Abstract
This paper discusses the mirror zone and path loss in the design of an EMC shielded anechoic chamber. Some beneficial suggestions and solutions are presented on the basis of the author's own experience. Then the selection of the wave-absorbing materials and the improvement of the shielded anechoic chamber's performance are studied. Finally, the prediction results of the mirror zone and the path loss of the shielded anechoic chamber in the National Key Laboratory of EMC are presented.
