Abstract:
The increase in the operating frequency of electronic equipment has led to increasingly serious electromagnetic radiation noise,and the shielding of the radiation noise by the shell is the most effective method. However,due to heat dissipation and wiring,the shell will have holes,which greatly affects its shielding effectiveness. After modeling the perforated enclosure,this paper obtains the results of the shielding effectiveness of the enclosure through CST simulation. According to the simulation results,the transmission line equivalent circuit model and the genetic algorithm-differential evolution(GA-DE)algorithm are used for parameter extraction,and the shielding effectiveness simulation results and algorithms are compared. As a result,the accuracy and reliability of the algorithm results are proved,and the influence of the distance from the hole surface on the shielding effectiveness is explored,which is of great significance to the actual shielding design.
