Abstract

An accurate and efficient method to predict the shielding effectiveness (SE) of a rectangular enclosure with rectangular apertures is presented. A more accurate mathematical disposal is suggested for the calculation of slot impedance. And the point is to replace the former approximate expression by rigorous elliptical integration. Finally, the predicted results of the new method are compared with measured data and good agreement is reported.
