FIELD: electricity. ^ SUBSTANCE: invention relates to electrical engineering and particularly portable shielded chamber design The invention may be used in research activities for assessing electromagnetic interference of different radio and electronic instruments. The side walls, top and bottom of the portable chamber are manufactured from current-conducting multi-layer corrugated material of "polymer film - current-conductive coating" type allowing for chamber stretching, compressing and smooth bending during installation at the working place. The content of multi-layer "polymer film - current-conductive coating"-Type material includes tape-like fragments absorbing electromagnetic radiation. The tape is manufactured from amorphous magnetic material. ^ EFFECT: reduction of chamber weight and cost, improvement of operation easiness due to avoidance of assembling and dissembling operations during chamber transportation from one room to another, preservation of required values of shielding effectiveness. ^ 2 dwg |
