ELECTROMAGNETIC SHIELDING EFFECTIVENESS - EFFECTS DUE TO GAP SIZE ANDANGLE OF CUT

Effects of various joint configurations and gap sizes on the electroma gnetic shielding effectiveness (SE) are evaluated to provide guideline s for best design of joints in order to increase the value of SE. Four different joint geometries are presented. A sharp decrease on SE with larger gap size for simple joints is observed. Addition of bends in t he joint geometry has strong positive effect on the value of the SE. I ncreasing the angle of cut, which increases the effective length of th e joint were also demonstrated to have increasing effect on the shield ing performance.
