A configuration of shielding current front in a superconducting thin plate under a perpendicular magnetic field He, can be well approximated by a curve for very thin film limit, having a theoretical expression based on the critical state model with constant superconducting current density Jc . Two parameters included in this curve expression may be determined by magnetic shield conditions, which are (1) zero field at the center of the plate, and (2) zero 2nd-derivative of the field variation near center. In the case of inverse aspect ratio α＝0.1,0.01,0.001,two parameters are calculated numerically, which processes require very careful treatment with the above condition (2) asαbecomes very small. Calculated results are estimated as how these curve parameters depend on He and α. On the basis of this estimation, we propose some formulas approximately fitting with calculated ones for wide range of He and α, which are useful for practical uses.
