Research on electromagnetic shielding of cavity with complex aperture structure

Aim for a better electromagnetic shielding, the shielding character of cavity with aperture/slot structure was researched, and complex aperture/slot shielding scheme was proposed. The aperture matrix structure was applied to increase aperture spacing and then weaken aperture coupling and coupled field; to strengthen the electromagnetic reflection, a staggered double layer shielding structure was considered; with the lengthen scheme of aperture path, the transmission consumption was strengthened dramatically; therefore the shielding performance was optimized finally. Simulation and result analysis proved the efficiency and practical value of the proposed scheme.
