Abstract

Shield Effectiveness (SE) is a most significant parameter that determines the electromagnetic compatibility (EMC) characteristics of the system. Calculation of this parameter is the prerequisite for understanding the standards of the system. Many techniques are implemented for the betterment of this parameter. In this paper, implementation of various perforated shield materials are proposed and their corresponding frequency responses are evaluated. Distance between the source of electromagnetic interference (EMI) and the system under test (SUT) has a direct impact on SE. Investigations by varying this distance is presented in this paper. The functioning of the material as shield in the presence of such environment is given.
