| Abstract: | The formulae for radial magneto-static shielding effectiveness of the double-layer cylindrical enclosure with magnetic material are derived based on the analysis of the single shell by the method of field theory, and the conclusion is validated by experiment, which offer the foundation of quantifica- tional calculation of shielding effectiveness of the double-layer or even more cylindrical enclosure. Based on the formulae derived, the affection to the shielding effectiveness when radius, thickness, and material of each layer are changed is also studied, especially the factor of the space between the two layers, which offer an important theoretic foundation for engineering application. |
