Abstract
Multi-layered Waveguide-Below-Cutoff Array(WBCA) used in air duct and water pipe has advantages in manufacturing process as well as flow characteristics. In addition, it is possible to increase the Shielding Effectiveness(SE) by increasing the number of layers. However, since the SE of the multi-layered WBCA can not be predicted by the conventional SE equation, we propose the modified SE equation. The modified SE equation is obtained for both air and arbitrary fluid flowing in a multi-layered WBCA by increasing the number of layers from 2 to 64. In order to confirm the validity, the results of the proposed SE equations are compared with the EM simulation results.
