Abstract
Numerical study of superconductor has been done by using Time Dependent Ginsburg-Landau (TDGL) to analyze the effect of variation on size of superconductor in the first critical field (Hc1) and the surface critical field values (Hc3) within the proximity effect. The object of this study is rectangular type-II superconductor with its variation on size of extrapolation length values are 3 and 10. The calculation of order parameter in this model used TDGL equation which finished by using ψυ method and proximity effect limit equation at the edge of superconductor. Results shown values of \\ψ′\\2 — Hext for every grid size variation. It also could be used to calculate Hc1 dan Hc3 by variation on size. We also concluded that the bigger size of superconductor made decreasing of Hc1 dan Hc3 values into a certain value until constant.
