Fields for a unit cell of , comprised of a solid circle: (a) solution to the homogenized problem, (b) concentration field transformed from , and (c) magnitude of concentration gradient (diffusion speed) and direction. The fields with respect to are the same as shown above but rotated by 90 degrees.
