Abstract: A new approach for generating sub wavelength scale one dimensional chain of magnetic spot, hole, flattop and bubble profiled segments using tightly focused phase modulated azimuthal and radial variant vector (ARVV) beam is proposed and investigated numerically using vector diffraction theory. Numerical result shows that by using a well optimized single Complex Phase Filter (CPF), one can generated and tune the geometry of the 1D chain of magnetic field distribution from sub wavelength scale hole to spot and then to a chain of flattop profiled and bubble structure segments by properly tuning the radial index of the incident azimuthal- and radial-variant vector beam. Such an approach is simple and usable for simulate condensed matter phenomena.
