FDTD analysis of electromagnetic penetration into a rectangular enclosure with multiple rectangular apertures

Abstract

The shielding effectiveness of a rectangular enclosure with multiple apertures is investigated using the finite‐difference time‐domain (FDTD) method. It is shown that increasing the number of apertures influences the shielding effectiveness of the rectangular enclosure. The arrangement of the apertures is found to affect the shielding properties as well. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 22: 188–191, 1999.

Benefits of using conductive plastics in shielding configurations to reduce radiated electromagnetic interference

“…Numerical methods have also been necessary when enclosures with noncanonical shapes, arbitrary distribution of surface apertures, and internal contents in the box have been analyzed. Transmission line matrix [3], finite difference time domain [4], and method of moments [5] are some examples of the methods used.…”

Fast computation of shielding effectiveness of metallic enclosures with apertures and inner elements

“…In [3] the Method of Moments was applied to obtain the shielding effectiveness of a metallic enclosure with more than one aperture, taking into account the effect of inner contents as metallic plates or absorbers. The Finite-Difference TimeDomain (FDTD) method for the study of the shielding effectiveness of a metallic box with apertures is evaluated in [4][5]. The analysis of inner elements, especially PCBs, has been realized through several tools.…”
