Abstract

The denser and higher speed telecommunication systems get, the more electromagnetic waves and more heat they throw off. With power predictions lastly for the upcoming systems, they need the enforced method to optimize the technologies between shielding effectiveness and cooling characteristics. In the present study, the shielding effectiveness and cooling characteristics for en- closures with multiapertures considered as fundamental solution in telecommunication systems are performed both of experimentally and unmerically. The shielding effectiveness measured from ex- perimental work is compared with both of the analytical data for flat plates with multi-apertures and the cooling characteristics by the numerical solution. As results, the most significant influence on the shielding effectiveness of enclosures is determined by the porosities of apertures, and it is found that shielding effectiveness and cooling capabilities are significant varied, reciprocally,at which porosity is more than 80%.
