This paper presents the electromagnetic scattering characteristics of an open nuclear power plant (NPP) cabinet at application frequencies of 2.4 and 5 GHz when the incident wave is parallelly polarized. The electromagnetic field strengths were investigated at each frequency and the corresponding shielding effectivenesses (SEs) were obtained. The SEs at 2.4 GHz were higher than those at 5 GHz; however, the differences were not significant. SEs calculated with a dielectric or magnetic wall introduced on the cabinet door were slightly improved compared to those without a dielectric or magnetic wall. The SE was also investigated with respect to the spacing between adjacent digital modules. The electric SE improved when the spacing from the suggested structure was increased by 20 mm. The findings are expected to be beneficial for designing NPP cabinets.
