In this paper, we introduce a concept of HEMP systems and analyze a shielding effectiveness by varying placements of the antenna elements. Maxwell's equations for the high frequency of the EMP is represented in the LOS. In order to investigate the effects of electromagnetic attenuations, a shielding room was constructed and employed to obtain measured data. The results of the paper can be applicable to design of concrete structures and the actual main protection facilities.
