The fully penetrated state of anisotropic superconductors which are extended in the c-axis direction is analyzed using a model to describe the current distributions. Based on magneto-optical investigations on a rectangular single crystal and on a cubic melt-processed YBa2Cu3O7-δ sample, the current distributions found in (a, b)-planes and (a, c)-planes with the external magnetic field perpendicular to the plane are discussed. The easy flux penetration along the CuO2 layers is shown to have important consequences for the analysis of angle-dependent magnetization or torque measurements in c-axis direction extended samples.
