Abstract
The shielding effectiveness of a planar multilayered screen is computed in the time domain in the presence of near-field magnetic sources. The proposed numerical method involves the efficient evaluation of classical Sommerfeld integrals and the inverse-Fourier transform through double-exponential formulas. For sufficiently thin screens with highly-conductive properties, an analytical method, based on a modified Cagniard-de Hoop approach, is also presented to validate the results.| File | Dimensione | Formato | |
