Abstract (2. Language): 
In this paper a hybrid formulation is presented which combines edge-based vector finite method (FEM) and Method of Moments (MoM) in frequency domain to predict electromagnetic field distribution inside an enclosure with aperture. While MoM is used for solving the surface integrals related with the aperture field components via equivalent surface currents, FEM is used for solving electromagnetic fields inside of the enclosure. Numerical results for shielding effectiveness and electrical energy of enclosure with aperture are calculated by the hybrid method and they are presented and validated with the existing literature. Then the method is applied to different enclosures with different aperture sizes.

Abstract (Original Language): 
Bu makalede, açıklığa sahip bir kutunun içerisindeki alan dağılımını bulmak için frekans domeninde moment metodu (MoM) ile kenar tabanlı vektörel sonlu elemanlar metodunu (FEM) birleştiren hibrit bir formülasyon sunuldu. Açıklıktaki sınır koşulundan elde edilen integral denklemin çözümü için moment metodu kullanılırken, kutunun içerisindeki elektromanyetik alanların çözümü için sonlu elemanlar metodu kullanıldı. Açıklığa sahip kutunun ekranlama etkinliği ve depolanan elektriksel enerji hibrit yöntem ile hesaplandı ve literatürdeki sonuçlar ile karşılaştırılarak doğrulandı. Daha sonra bu yöntem farklı açıklık boyutlarına sahip farklı kutulara uygulandı.
