Short summary
Electric equipment can be shielded against high power electromagnetic fields via metallic cavities. At certain frequencies, called resonances, the shielding effectiveness collapses. In this paper the impact of different sized windows in the shield is analyzed. The results is: at a certain size of the window, approximately one third of the shield's size, the shielding effectiveness is at its minimum. Furthermore, the quality factor of shields with different windows sizes is analyzed.
