Abstract: Modern electric devices always work in complicated electromagnetic environment. Although some shield measures, when an incident electromagnetic pulse acts on a certain device in the system, other devices may be affected. In this paper, a complicated system is represented by a transmission line network topology model, and its response to the electromagnetic excitement is analyzed using BLT Equation. And this paper gives an example of? three typical system configurations.
Key words: BLT Equation；Transmission Line Network；Electromagnetic Excitement；Node Scattering Matrix； systemic configuration
