Description
Summary:This paper proposes an improved thickness correction method for circuital models that can predict the shielding effectiveness analytically. This method considers the thick aperture as a short section of waveguide separating the two interfaces of its ends and treats only the dominant mode in this section. It is found that the improved correction method can generate more accurate shielding effectiveness than the traditional method. In all the examples, the accuracy of the results is validated by the transmission line modeling method.
