This paper investigates the Electromagnetic(EM) shielding effectiveness and proposes a method of predicting it in. the case of employing slit-shaped joints between electrically conductive shielding material sheets or films in EM shield rooms. Slit-shaped joints have overlaps between adjacent conductive materials and are fastened by screws or similar means. The total slit length, fastener pitch, lap width, electrical conductivity of the two overlapping materials and openings that often need to be cut-out in the shielding materials (for the purpose of installing electrical or other utilities) are the factors that are expected to influence the shielding performance. The current investigations reveal that all of the above factors except the lap width give significant influence on the shielding performance.
