    • Fourier transforms of fractional order and their optical interpretation 

      Özaktaş, Haldun M.; Mendlovic, D. (Elsevier, 1993)
      Fourier transforms of fractional order a are defined in a manner such that the common Fourier transform is a special case with order a=1. An optical interpretation is provided in terms of quadratic graded index media and ...
