Abstract

Elektromanyetik ekranlama, elektronik cihazların elektromanyetik yayınımlarını azaltarak ve harici elektromanyetik girişime (EMI) karşı bağışıklıklarını artırarak elektromanyetik uyumluluk (EMC) performanslarını iyileştirmeyi amaçlar. Ekranlama performansı, ekranlama kutusu yokken ve varken ölçülen alan büyüklerinin (elektrik veya manyetik) oranıyla ifade edilen ekranlama etkinliği ile belirlenir. Bu çalışmada, ön panelinde açıklığı olan metalik ekranlama kutusunun manyetik ekranlama etkinliği (MSE) analizi 0-2 GHz aralığında gerçekleştirilmiştir. Açıklığın, ekranlama kutusunun ön panelinin merkezinden üst köşesine taşındığı durumda MSE’de iyileşme elde edilmiştir. Açıklığın, ön panelin üst köşesinde olduğu durumda ekranlama kutusu boyutları, açıklık boyutları ve gözlem noktasındaki değişimlere göre MSE analizleri gerçekleştirilmiştir. Ekranlama kutusu boyutlarındaki artış MSE üzerinde iyileşme sağlarken, açıklık boyutlarındaki artış MSE’yi zayıflatmıştır. Gözlem noktası, açıklıktan uzağa taşındığında ise MSE’nin arttığı elde edilmiştir.

A Study on Magnetic Shielding Parameters of Metallic Shielding Enclosure with Aperture

Abstract

Electromagnetic shielding aims to improve electromagnetic compatibility (EMC) performance of electronic devices by reducing electromagnetic emissions and increasing their immunity against external electromagnetic interference (EMI). Shielding performance is determined by shielding effectiveness, expressed as the ratio of measuring field magnitudes (electric or magnetic) with and without the shielding enclosure. In this study, magnetic shielding effectiveness (MSE) analysis of metallic shielding enclosure with an aperture on the front panel is performed in 0-2 GHz range. Improvement on MSE is obtained when the aperture is moved from the center to the top corner of the front panel of the shielding enclosure. In case of locating the aperture at the top corner of the front panel, MSE analyzes are carried out according to the changes on shielding enclosure dimensions, aperture dimensions and observation point. While the increase on shielding enclosure dimensions improves MSE, the increase on aperture dimensions attenuates MSE. It is obtained that MSE increases when the observation point is moved away from the aperture.
