摘要：
The shielding performance of a metallic building located close to a telecommunication tower hit by lightning is investigated. Two models of lightning strike are adopted for the shielding analysis. The first model includes the current distribution along the lightning channel while the second model is a surge current injected into the top of tower only. For each model the performance is evaluated both in the frequency domain and in the time domain. The analysis reveals that the electric shielding effectiveness is highly affected by lightning models whereas its magnetic counterpart remains invariable.
