Abstract In this paper, we measure the leakage through aperture and the material’s
shielding effectiveness, which are familiar in the structure design, by the standard
method for measuring the effectiveness of electromagnetic shielding enclosure. Through
the measure, we can gain the data, which is helpful for engineers to select the
shielding material and design the products. The method refers to the MIL-G-83528 and
IEEE Std 299-1997.
