Mappings of the Ps vectors across the 90° NCDW and 90° UCDW.
(a) Ps vectors of 90° UCDW and 90° NCDW away from PTO/STO interface. Note the bifurcation of the Ps and the trend of diagonal Ps directions (marked with red arrows) across the 90° NCDW. (b) Ps vectors across the 90° NCDW near the PTO/STO interface. It is seen that the scattering of the Ps vectors at this 90° NCDW makes the “wall” into a “band”. In (a) and (b), the length of the yellow arrows represents the modulus of the Ps with respect to the yellow scale bar in the lower left corner.
