Abstract

This paper presents a detailed study of the shielding effectiveness properties of rectangular enclosures with apertures, by using a numerical method (FDTD). Both the magnetic and electric shielding was calculated as a function of frequency, enclosure dimensions, different apertures shapes, plane wave incidence mode and positions within the enclosure. Also the “loaded aperture” approach was investigated. The results of shielding effectiveness predictions obtained by the numerical method are compared and validated with full-field simulations using software CST.

矩形孔罩屏蔽效能的数值研究
本文采用时域有限差分法(FDTD)对带孔矩形外壳的屏蔽效能特性进行了详细研究。根据频率、箱体尺寸、不同孔径形状、平面波入射方式和箱体内位置的函数计算了电磁屏蔽。并对“加载孔径”方法进行了研究。将数值方法得到的屏蔽效能预测结果与CST软件的现场模拟结果进行了比较和验证。
