摘要: A simplified theory of electromagnetic shielding by enclosures with conductive and/or magnetic wails is presented. The based on a type boundary condition at the enclosure walls. Theoretical results are compared exact solutions for steady-state and transient excitation approximation turns out to be extremely good in all cases practical interest. For arbitrary shapes, problem formulated as single integral equation unknown current shield. Numerical solution discussed, well possible equivalent lumped-circuit representation.
