Abstract:
In this paper, the Transmission Line Matrix (TLM) method is used for the electromagnetic characterization of the Shielding Effectiveness (SE) of rectangular enclosures with apertures of arbitrary shape. Applying suitable Hanning windows in the time domain drastically reduces the number of time steps required to model the coupling behavior of resonant enclosures. Comparison of the numerical results with available measured data shows that the method is an efficient and accurate technique to evaluate the shielding effectiveness of metallic shields in the time domain and over a wide frequency range. The proposed method can be used as an intermediate design tool for the evaluation of the effects of various aperture shapes on the effectiveness of shield assemblies
