AB - A 2-D version of the generalized circuital analysis
(GCA) has been used along with the finite element method (FEM)
to estimate both the radiated perturbation produced by an arbitrary
current distribution (represented by a set of linear current
sources) covered by a slotted enclosure, and the field coupled to a
slotted screen due to a radiated perturbation. The effect of a given
enclosure is modeled by means of a scattering matrix (which depends
only on its geometry) obtained by the FEM. On the other
hand, any arbitrary perturbating field can be expanded in a series
of cylindrical harmonics, and then, the total field is computed
everywhere using the scattering matrices. This method has the advantage
over conventional FEM approaches that FEM is applied
only once, and then a wide range of electromagnetic compatibility
(EMC) problems can be solved with almost no extra computational
effort. Two-dimensional models of relevant EMC problems involving
both emission and immunity have been studied in order to
extract useful information for actual 3-D systems. In spite of the
2-D approach, very interesting conclusions can be derived fromthe
examples presented in this paper (like the effect of slot resonances
in the field distribution within slotted enclosures or the coupling
between two connected cavities).
