Finite extension shields are analyzed against transient magnetic fields produced by lightning phenomena. The shielding performances of finite width PEC shields are calculated by the FEM for eddy current problems and by the FDTD method for wave propagation problems. The analysis is also carried out for penetrable shields by imposing impedance network boundary conditions (INBCs) in the numerical methods. The results obtained for PEC and penetrable shields are compared against current line and plane wave field sources.

Abstract
Finite extension shields are analyzed against transient magnetic fields produced by lightning phenomena. The shielding performances of finite width PEC shields are calculated by the FEM for eddy current problems and by the FDTD method for wave propagation problems. The analysis is also carried out for penetrable shields by imposing impedance network boundary conditions (INBCs) in the numerical methods. The results obtained for PEC and penetrable shields are compared against current line and plane wave field sources.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
