      Horvath, Zoltan L.; Erdelyi, Miklos; Szabo, Gabor; Bor, Zs.; Tittel, Frank K.; Cavallaro, Joseph R. (1997-11-01)
      A new concept for generating zero-order Bessel beams was studied theoretically. The spatial intensity distribution was calculated numerically using a wave optics model. Approximate analytical expressions were derived to ...
