摘要
Abstract
A method joining waveguide out of the shield structure is presented,by using the effect of the attenuation of high-frequency electromagnetic waves in waveguide to improve shielding effectiveness. Finite element method is used to modeling and simulation of the waveguide length,thickness and the shape. The simulation results show that:in the range of the 0.1 GHz~1 GHz frequency,the shielding enclosure shielding effectiveness with the increase of length and thickness of the waveguide has improved 15 dB and also improved a little on the rectangular and circular waveguide. According to the actual situation to choice a reasonable length and the thickness of the waveguide,the electromagnetic immunity of the weak signal processing circuit can be improved.关键词
