According to the theory of EMC （electromagnetic compatibility） and the requirement of ruggedized cabinet structure design, the paper describes the influence of apertures or holes in cabinet on electromagnetic shielding, proposes some specific measures to ensure the electromagnetic shielding performance and anti-electromagnetic-interference performance of the cabinet structure, which effectively solve the problems exist in EMC design. Finally, the experiment result proves the improvement of the electromagnetic shielding performance when the proposed measures are adopted.
