Abstract

In this study, the
time-domain vector finite element method (TDFEM) was used to
calculate the electrical shielding effectiveness of electronic device
boxes with aperture. The results obtained were compared with the literature and found to be
compatible. With an effect of reducing the quality of the protectors,
radiation fields from aperture are not desired. The change in shielding
effectiveness has been investigated by inserting perfectly conductive wires and
part conductors on the aperture. A boost of about 20 dB between 500-900 MHz has
been achieved.

Abstract

Bu çalışmada açıklığa sahip elektronik cihaz kutularının
elektriksel ekranlama etkinliğini hesaplamak için zaman domeni vektör sonlu
elemanlar metodu (TDFEM) kullanılmıştır. Elde edilen sonuçlar literatür
ile karşılaştırılmış ve uyumlu olduğu görülmüştür. Açıklıklardan ışıyan
alanlar, koruyucunun kalitesini düşürdüğü için istenmemektedir. Açıklık üzerine
mükemmel iletken teller ve parça iletkenler yerleştirilerek ekranlama
etkinliğindeki değişim incelenmiştir. 500-900 MHz arasında yaklaşık 20 dB’ lik
bir ekranlama artışı sağlanmıştır.
