要約(Abstract) :When a magnetic field is applied obliquely to the surface of a superconducting plate,a shielded region is formed in its interior space surrounded by shielding currents. In case of a plate having infinitely small thickness,a configuration of the current front can be well described by a model proposed by G.P.Mikitik,E. H.Brandt et.al.􀀁􀀂In order to investigate the applicability of this current model to a thicker plate,the center field produced by the current distribution is calculated numerically in low and medium range of external field, which does not cause full flux penetration to the plate center. As is expected for this model, a magnitude and an angle of the remaining field in the center are very small in a small range ofα,whereαis defined by the ratio of a plate thickness to its width. However,these values build up and magnetic shielding becomes incomplete when αis larger than 0.1. As a result, it can be concluded that this current model is not applicable forαlarger than 0.17, for which an other adequate model will be
