AB  - We have proposed a kind of modified circular Airy beam (MCAB) based upon a 
      modification of the Fourier spectrum of circular Airy beams (CAB) in this paper. 
      Unlike most abruptly autofocusing beams, the position of peak intensity of MCAB 
      can be moved to any rings behind. Two apodization parameters are introduced to 
      describe the propagation characteristics of MCAB. It is found that the focal 
      position, focal trajectory and the size of focal spot do not change with the 
      apodization parameters; but the abruptly autofocusing property will be greatly 
      enhanced if appropriately apodization parameters are chosen. Comparing with the 
      common CAB and the previous blocked CAB, the MCAB shows better abruptly 
      autofocusing property. It may have more applications in various fields.
