Abstract:
Using FDTD numerical simulation and a near-field scanning optical microscope with metallic cantilever it was shown that linearly-polarized plane wave diffracted by an angular glass step with the width of 2λ (λ – wavelength) forms slow divergent hyperbolic “photonic jet” with length of higher intensity being 9.5λ and diameter of 1.8λ along a distance of 5.5λ. The maximum intensity is 5 times larger than the intensity of input wave. Results of the numerical simulation differ from experimental data by 11%. It was shown that diffraction patterns by the angular phase step and by an opaque screen with a hole instead the step are equals.

Key words:
photonic jet, dielectric step.
