Abstract

We report unique quasi-one dimensional (1D) Bessel-like beam formation from a sub-wavelength slit embedded in 1D periodic metallic grooves. Finite-difference time-domain analyses and composite diffractive evanescent wave model provided a good explanation of the unique beam-shaping phenomena.
