Abstract
The efficiency of conductive and magnetic screens is analyzed in the large scale shielding of environmental magnetic fields up to 20 kHz. Several geometrical configurations of the shields and the field sources are reproduced in laboratory in order to analyze in a systematic way the mitigation properties. The problem is also faced by a numerical model, based on a hybrid FEM-BEM approach.
