초록

This paper investigates the effect of a corrugated aperture on a common-mode current traveling along a penetrating wire. Computational results illustrate that the corrugated aperture acts as a filter, significantly reducing the common-mode current on the wire. This effect causes a reduction of radiated emission from cables passing through apertures on shielding enclosures. To predict and analyze the characteristics of the common-mode current on a straight wire passing through a corrugated aperture with cylindrical symmetry, the finite-difference time-domain (FDTD) method is applied.
