通过实验,讨论了多点平均法和单点平均法的可重复性;利用多点平均方法,对带不同尺寸开孔的金属腔体内部耦合场强进行测试;在此基础上对带不同尺寸开孔金属腔体的屏蔽效能进行计算。最后采用插值拟合方法,对上述实验进行了数值模拟,以200mm×40mm开孔为例计算了腔体内部耦合场强及腔体的屏蔽效能。
Through experiments, the repeatability of multi-point averaging method and single-point averaging method are discussed. The multi-point average method is used to test the internal coupling field strength of metal cavities with openings of different sizes. Based on this, The perforated metal cavity shielding effectiveness is calculated. Finally, interpolation experiments were carried out to simulate the above experiment. Taking the 200mm × 40mm open hole as an example, the coupling field strength and the shielding effectiveness of the cavity were calculated.
