 note = {Electromagnetic shielding is popularly used to suppress electromagnetic noise generated from electronic equipments. It is important to know the shielding mechanism in designing the effective shielding. In this paper, the electromagnetic field in the vicinity of a horizontal multilayered medium with either a magnetic or an electric dipole source was calculated theoretically by a Sommerfeld integral, in which a spherical wave radiated from the dipole source is expanded into a large number of cylindrical waves. The integration formulas are derived and they are numerically calculated for investigation of shielding effectiveness and Poynting flux. We calculate electromagnetic shielding effectiveness to confirm the applicability of this analysis. Calculation results are in good agreement with measurement results. To clarify the shielding mechanism, Poynting flux from either a magnetic or an electric dipole source in the vicinity of shielding materials and inside the shielding materials is demonstrated. The electromagnetic wave with the shield is attracted by the shielding material, and shielding effectiveness depends on energy flow along the shielding material.},
