Reduction of /spl Lt/back-door/spl Gt/ radiative coupling, review and analysis of classical methods and study of an innovative technique

Techniques of back-door radiative coupling limitation are reviewed, including microwave gaskets and special assembling methods. These techniques help one to protect electronics against high frequency electromagnetic radiations like radar or high power microwave (HPM). An other way consisting of absorbing material placed into the equipment box is also examined. Measure of shielding effectiveness prove the efficiency of this technique, which has to be taken in account with statistical electromagnetic (STEM) tools.
