| Abstract: | The electromagnetic coupling of an incident plane wave through some small apertures into a shielding cavity is studied. By using the equivalence principle and the method of moments, the generalized network matrix equations are worked out. The shielding coefficients of a plane wave verticaly incidented on a conducting cavity with some small apertures are obtained. The cases of single aperture and two apertures are calculated in numerical examples, and the influence of frequencies and the location, the dimensions, the shape of the apertures on the shielding effectiveness is discussed. |
