Archimedean spiral 3D super-resolution longitudinal MS array. (a) Phase pattern of the MPFs with G=18. (b) 3D iso-magnetization surface of the MS array with M=Mmax/2. (c and d) Perspective views of the total magnetization field in the xy and rz planes. (e) Relevant magnetization cross-section profiles in c and d, respectively (black and red lines are the magnetization cross-section profiles in the array along the x and z axes, respectively. The blue line represents the magnetization pattern of a single focal spot without the MPFs along the x axis). (f) Enlarged view of individual MS inside the array and its polarization distribution in the rz plane.
