| Abstract: | The calculation approach of shielding effectiveness by spectral-domain analysis is introduced in this paper. Focusing on the periodic structure of aperture arrays with rectangular shape, shielding effectiveness is analyzed and calculated by the spectral-domain method. And the simulated analysis and computation of a periodic structure of aperture arrays with rectangular shape in a conducting fiat screen are compared by spectral-domain method, FDTD and testing. As the theoretical analysis and simulation results shown, the shielding effectiveness of aperture arrays is a very good agreement between simulated and measurement results. |
