Description
Summary:An efficient lightweight modeling method was examined to analyze the shielding characteristics of large-scale models such as real-world buildings, and the findings were verified based on the relevant standards. In general, electromagnetic threats with high energy can cause severe damage by causing malfunctioning and system failure of electronic systems. To protect electronic systems, the shielding characteristics of the building in which the systems are located must be clarified. Extensive research has been conducted on the shielding characteristics of building materials and reinforced concrete. However, only a few researchers have adopted a simulation-based approach to analyze and verify the shielding characteristics of actual-scale reinforced concrete buildings up to the gigahertz (GHz) band. Therefore, in this study, a lightweight 3-D modeling method was used to analyze large-scale models such as buildings up to the GHz band. The shielding characteristics of the building were determined using the proposed approach, and the results were compared and verified against measurement data using feature selective validation. Furthermore, the proposed method was used to analyze the shielding characteristics of a reinforced concrete building pertaining to the transmission and reflection characteristics of reinforced concrete walls.
