REDUCTION CHARACTERISTICS Of ELECTROMAGNETIC PENETRATION THROUGH NARROW SLOTS BY RESISTIVE SHEETS LOADING

장하 저항시트의 구조변화에 따른 슬릿 침투 전자파 저감특성

This paper presents the reduction methods of penetrated electromagnetic fields through a narrow slot aperture in a planar conducting screen of infinite extent. When a plane wave is excited to the narrow slot, the aperture electric field is controlled by the resistive sheets loading on the slot. The magnitude of the penetrated electromagnetic fields through a narrow slot is controlled by electric field distributions on the slot aperture. The results show that the magnitude of the penetrated electromagnetic field can be effectively reduced by the resistive sheets on the slot aperture.
