Abstract
Shielding electronic circuits from electromagnetic interference (EMI) is crucial in the aerospace industry, particularly for space vehicles, as EMI can have significant impacts on the functioning of various devices. Shielding effectiveness (SE) is the industry-standard measure of EMI shielding. This study aims to evaluate the SE of three types of infinite sheet metals against magnetic, electric fields, and plane waves generated by the electromagnetic pulse from a system. Maxwell's equations were used to calculate the SE to determine whether the selected tapes conform to the 40 dB SE requirement specified in electromagnetic compatibility (EMC) specifications. Using MATLAB, absorption loss, reflection loss, re-reflection correction factor, and SE were computed. The findings highlight the importance of proper EMI shielding in aerospace design and demonstrate how different sheet metals can provide varying levels of protection against EMI.
